README: update windows build instructions for eigen, python
The recent addition of "eigen3" to nextpnr necessitates the addition of
"eigen" to the list of vcpkg packages to be installed on Windows.
Add the 32- and 64-bit versions of eigen to the command issued to
install various dependencies.
Also document one possible build command, and note about unpacking
python36.zip.
