Precision watch update (#152)
* Intermediate changes * Databank working * Main commit for precision timing First version where all functions are supposed to be working * Fix math error in nanosec. File storage for location. * Remove obsolete comments * Missing page name on pages rotation - thanks to jeremy * Delete file.diff * Cleanup+tempchart 1) finetune must always reset last calibration time when doing non-0 time correction, even when you are not applying ppm correction. 2) Dithers over 31 periods not 10, more resolution with still no risk of overflow 3) Minute-boundery finetune fix. I also just got this 1-minute error after finetune... 4) Write frequency calibration value in 1 operation rather than 2. All RTC writes must be single operations to avoid partially correct data. 5) Some code cleanup 6) Tempchart face is added for temperature statistics * Update set_time_hackwatch_face.c * Math error in display code of finetune, allow to update correction time even without correction - by long alarm press * Increase reliability of stopping & starting RTC timer As it's quite dangerous operation * hackwatch - days adjust down fix by long alarm * unify style * More comments & last style change * Simulator support RTC operations (watch_rtc_enable and watch_rtc_freqcorr_write) are in common libs. * Unicode fix * Crystal aging is now adjustable (AA page in nanosec - annual aging, ppm/year) Aging is baked into fixed offset every time finetune is performed, as it relies on last adjustment time. * Blink on non-0 page every minute in finetune to measure clock error * Rolling back private changes * Cleanup * Cleanup * Quality of life changes in nanosec 1. Does not calculate & apply ppm correction if less than 6 hours passed since previous adjustment (as it gives very high correction values which are unrealistic and unhelpful) 2. Idle timeout resets to face 0 only if no correction was made * unify style * Fix low-power errors in nanosec infrastructure, faster display in finetune * Merge fix * unify style Co-authored-by: Jeremy O'Brien <neutral@fastmail.com> Co-authored-by: joeycastillo <joeycastillo@utexas.edu>

+ * FineTune face allows to align watch with sub-second precision in 25/250ms accuracy.
+ * Counts time since previous finetune, and allows to calculate & apply ppm correction for nanosec.
+ *
+ * Main screen - adjust delay (light/alarm)
+ * Long mode press - show hours since previous finetune
+ * Long mode press - show calculated ppm correction. You can apply it with long light, or just reset finetune timer with long alarm.
+ *
+ * Finetune will apply crystal aging correction on every finetune save (as aging is calculated since "last finetune" timestamp) - but you should worry
+ * about aging only on second/third years of watch calibration (if you are really looking at less than 10 seconds per year of error).
+ *
+ * Warning, do not use at the first second of a month, as you might stay at the same month and it will surprise you.
+ * Just wait 1 second...We are not fully replicating RTC timer behavior when RTC is off.
+ * Simulating months and years is... too much complexity.

+ * The goal of nanosec face is dramatic improvement of SensorWatch accuracy.
+ * Minimum goal is <60 seconds of error per year. Full success is if we can reach <15 seconds per year (<0.47ppm error).
+ *
+ * It implements temperature correction using tempco from datasheet (and allows to adjust these)
+ * and allows to introduce offset fix. Therefore requires temperature sensor board.
+ *
+ * Most users will need to apply profile 3 ("default") or 2("conservative datasheet"), and tune first parameter -
+ * static offset (as it's different for every crystal sample).
+ *
+ * Frequency correction is dithered over 31 correction intervals (31x10 minutes or ~5 hours), to allow <0.1ppm correction resolution.
+ * 1ppm is 0.0864 sec per day.
+ * 0.1ppm is 0.00864 sec per day.
+ *
+ * To stay under 1ppm error you would need calibration of your specific instance of quartz crystal after some "burn-in" (ideally 1 year).
+ *
+ * Should improve TOTP experience.
+ *
+ * Default funing fork tempco: -0.034 ppm/°C², centered around 25°C
+ * We add optional cubic coefficient, which was measured in practice on my sample.
+ *
+ * Cadence (CD) - how many minutes between corrections. Default 10 minutes.
+ * Every minute might be too much. Every hour - slightly less power consumption but also less precision.
+ *
+ * Can compensate crystal aging (ppm/year) - but you really should be worrying about it on second/third years of watch calibration. *

+ * This is an extended version of set_time face which allow setting seconds precisely.
+ * To achieve that - press and hold alarm button few seconds before 00 and release exaclty as reference clock turns 00.
+ * All settings can go up, or down (long alarm press).
+ *
+ * The challenge is that SensorWatch display is delayed 0.5 seconds vs hardware RTC clock. It is caused by interrupts being generated by raising
+ * edge of counter. It means there is no way to precisely trigger at 0.5s, as events at different frequencies slightly mismatch.
+ * This watch face achieves this approximately by triggering at 15th out of 32Hz events.
+ *
+ * If you are <30 seconds when setting seconds - you will stay in the same minute. Otherwise - you will go to next minute.
+ *
+ * Note that changing anything will slightly delay subseconds counter. This is why this face sets seconds last
+ * to achiveve best precision. Still, best possible precision is achieved with finetune face.
