Multiple enum value options not allowed

[bufdev]

This is valid per the Protobuf spec, but there is only one ValueOption *Option allowed on EnumFields. If you have this:

enum Something {
  SOMETHING_FOO = 0 [
    (bar.enum_value_option) = true,
    (bar.enum_value_dep_option) = { hello: 1 }
  ];
}

The error found "," but expected [option closing ]] is returned.
