Add OID for RSASSA-PSS X.509 signature algorithm (RFC 4055) (#4294)
In 2005, IETF devised a more secure padding scheme to replace PKCS #1
v1.5. To make sure that nobody can easily support or use it, they
mandated lots of complicated parameters in the certificate, unlike any
other X.509 signature scheme.
https://tools.ietf.org/html/rfc4055
`_SIG_OIDS_TO_HASH` and `Certificate.signature_hash_algorithm` cannot be
supported as-is, because the hash algorithm is defined in the signature
algorithm parameters, not by the OID itself.
