Thought that it was a nice addition to the
CirceStringEnumto be able to be used as a key inMaps (i.e.:Map[MyEnum, Int]).For that, Circe requires a
KeyEncoderand aKeyDecoderto be present in the implicit scope. With current enumeratum's API, implementing those is trivial for enums that are based on strings, so it could be cool to provide it out of the box.
