Casing issues

There seem to be a few issues with casing and the way things are generated:

This causes classes to not exist in the way that cpp expects them to be

Duplicate fields

Two of the same field are created if one of the original fields. E.g _radius and radius both become radius in a codegen header

Any way to skip invalid names?

Eg: Skip the following:

System.IO.IOException: The filename, directory name, or volume label syntax is incorrect. : 'D:\Il2Cpp-Modding-Codegen\Codegen-CLI\bin\Debug\netcoreapp3.1\output\include\<PrivateImplementationDetails>{FF33C43E-3513-4C16-A62D-5F1EFE332B71}'

Union size issue

As demonstrated in this file Unions still cause issues,

here the issue is that the union of MapType and the 4 quants is seperated out into fields, causing it to mess up the size check for the object. This means that the generated project does not compile due to the size checks there.

A hacky fix is of course removing the size checks there, but eventually properly having unions is the expection (I assume)

Just putting this in so it's an issue that can be tested on

Resolve Vtable slot issue with generic base class

if the base class of a type is generic, and that is the type that a vtable slot needs to be resolved for, the generic parameter is lost in the source file, example:

// header
class A : B<float> {
    void thing();
}

// source
void A::thing() {
    ...
    ___internal__method = resolveVtableSlot(this, classof(B<T>*));
    ...
}

obviously this is very simplified but I hope this makes the issue clear enough to understand.

the B<T>* should obviously be B<float>* there.
