feat: Enum: Add EnumConverter with underlying type lookup

[riffy]

Add enum support. Only supports enum numbers

Thanks for the PR!

Have you tested this between client and webview? I think it might not work because webview only considers double for number types, that was why if you have a look at numeric converters, they are all casted to double for that reason to keep the compatibility.

I've not tested it with a webview, but since all numeric enums are now casted as doubles, this shouldn't be a problem

Actually, string/char enum isn't a real thing in C# so you can simply get rid of it for this PR. Can you update it so that it just has the underlying type only please? This looks good to be merged without the string/char thing.

I had an initial idea of supporting enum serialization as string that you would annotate your class/property with [MValueMapEnum(EnumMappingStrategy.ByName)]. The converter then uses enumValue.ToString() for write, and Enum.Parse<YourEnum>(reader.NextString()) for read.

I have removed bool, string and char. Only (double) casting is left.

Perfect, thanks!
