Enum Prefix is not stripped

[bschug]

According to the Style Guide, protobuf enums should have the enum name as a prefix for all enum values, to avoid naming conflicts in languages like C, where all values from all enums are in the global namespace. Protobuf compilers for languages with scoped enums like C# will strip these prefixes if they match the enum name. Since enums in betterproto are scoped as well, these prefixes should be stripped.

Example:

enum ArithmeticOperator {
    ARITHMETIC_OPERATOR_NONE = 0;
    ARITHMETIC_OPERATOR_PLUS = 1;
    ARITHMETIC_OPERATOR_MINUS = 2;
}

should become

class ArithmeticOperator(betterproto.Enum):
    NONE = 0
    PLUS = 1
    MINUS = 2

so that we can use it as

if something.operator == ArithmeticOperator.PLUS:
     do_addition()

instead of

if something.operator == ArithmeticOperator.ARITHMETIC_OPERATOR_PLUS:
    do_addition()

I'm happy to make a PR for this

This should be fixed by #187 :)

This his a huge deal for my team. Can we have an ETA?

Thanks the the meantime I've been using your branch @Gobot1234 with no issues

Should be soon hopefully I just needed a re-review from Nat.
