Add optional encryption of checkpointer payloads
...
- no dependency on any particular encryption lib (there is no py stdlib encryption lib)
- works with any modern checkpointer, ie. those which use dumps_typed and loads_typed methods to serialize data
- backwards compatible with unencrypted data in same storage (will just be read unencrypted)
- providing easy constructor to use AES encryption through pycriptodome library, one single line of code to add it in
- other encryption libraries or algorithms (even assymetric ones) can be used by implementing the two-method CipherProtocol interface
- cipher name (eg. aes) is stored with encrypted payload for forwards compatibility
