[FINCH] no enum support

Description

The Finch code generator does not support enums. An inline enum generates a normal variable of the desired type; a referenced enum generates an empty case class.

Suggest a Fix

As far as I know there is no single best implementation choice for enumerations in scala. Possible choices are:

• scala enumeration class (no warning for non-exhaustive match, type erasure issues)
• sealed case objects (no easy way of iterating through values, no default serialization / deserialization) The serialization issue might not be a problem if circe supports it; still, scala enumerations might be easier to implement.
