Super-cereal

New:
* Adjusting `Encrypted` to hide the value when using `str` or `repr` (so logging doesn't leak encrypted info).

New:
* Adding support for Enum's

Fixed:
* Encryption with strings (specifically the str type).

Also fixed DictCerealizer to passthru a `dict` type instead of trying to inspect it like an object.

Initial alpha with support for serializing `dataclass` objects for JSON and Avro. Also including support for encrypting specific fields.
