Enhancement: Support Various Meta for Class Access Modifiers

[AndrewDRX]

Request

Add support for the following meta for class access modifiers:
@:file for file
@:internal for internal
@:public for public

Suggested Syntax

The syntax could be as follows:

@:public
class MyClass { }

To generate C# as follows:

public class MyClass { }

Details

Currently, classes are generated with no access modifiers. C# has the default modifier of internal when not specified, so all generated classes effectively have that modifier. This makes it impossible to develop a library package since all generated classes would be inaccessible when references by other projects.

Suggested Code Change

I can submit a pull request to show a rough idea of what this would look like.

Other Notes

There are also other class access modifiers (and accessibility levels) that would be applicable to nested classes, but I am not sure about the feasibility of generating nested classes, so those are excluded from this request.

I think this is a good thing to add, but better wait for my current ongoing changes before submitting a PR

Okay. I noticed this logic in CSClass.hx:

// Compile metadata (built-in Reflaxe function)
var clsMeta = compiler.compileMetadata(classType.meta, MetadataTarget.Class) ?? "";
declaration += clsMeta;

// Basic declaration
declaration += "class " + csClassName;

So I was wondering if there was some existing process for adding/updating a metadata template where that would be able to handle it.

But I'll wait on investigating any changes for pull request until you are all set.
