Added generator code

[Oliver-Quail]

Description

In this PR, I have added a code generator that works automatically with the api.json to generate the bindings for C#.

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

I have tested the output script with the current generation pipeline with no errors. I have then tested the output in SplashKit Online with C#

Hey oliver

Hey! Nice work on this — looks like you put a lot of effort into the struct generation and method mapping. The filtering logic makes sense, and it's cool to see how you're handling the SplashKit bindings. Great job 👍

I tested the branch locally and the CSharpWasm project builds successfully without warnings.

I approve the PR :)

Overall, this is a strong and well-focused pull request. Introducing a generator based on api.json to produce C# bindings is a solid improvement that will significantly reduce manual maintenance and improve long-term consistency.

Before merging, I recommend addressing a few points:

Please investigate and remove any hidden or bidirectional Unicode characters flagged by GitHub.

Since a generated file is committed, it would be good to document the generation process and ensure it is deterministic (ideally with a CI check to prevent drift).

The hard-coded path in CSharpCodeRunner.cs should be confirmed to be correct for all environments or made configurable to avoid future maintenance issues.

Once these points are addressed, this PR will be a valuable and maintainable addition to the project.
