core (memory/crypto): replaced `PyCrypto` by `cryptography`:
`PyCrypto` is unmaintained for years but was used in SàT for password hashing. This patch
fixes that by replacing `PyCrypto` by the reference `cryptography` module which is well
maintained.
The behaviour stays the same (except that previously async `hash`, `encrypt` and `decrypt`
methods are now synchronous, as they are quick and using a deferToThread may actually be
more resource intensive than using blocking methods).
It is planed to improve `memory.crypto` by using more up-to-date cryptography/hashing
algorithms in the future.
PyCrypto is no more a dependency of SàT
