Generated enum type case names are not capitalized like originals

[LyndonGingerich]

It seems that

enum MyEnum {
  MySingleEnumCase = 0;
}

would generate

type MyEnum =
| [<global.Google.Protobuf.Reflection.OriginalName("MySingleEnumCase")>] Mysingleenumcase = 0

with only the first letter capitalized.

I am glad to offer whatever assistance I can in finding and repairing this apparent bug. For now, I'll wait for reply since this repository does not seem to see much activity.
