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 👍
