remove quotes around printed enums

[nimrof]

Having problems reading enums with quotes around them user the official c++ implementation, removing them fixes the problem.

I can make this optional if wanted.

official examples of this can be found here: https://protobuf.dev/reference/protobuf/textformat-spec/#text-format-files https://protobuf.dev/reference/protobuf/textformat-spec/#example

I have problems finding any prof that this is the case in the c++ code The best prof i found is to look in the test file below and search for enum https://github.com/protocolbuffers/protobuf/blob/3667102d91bba05afcb777aa685b1014f521e9bc/src/google/protobuf/text_format_unittest.cc
