[Feature] Catmul Rom Splines and Bezier Curves

[loopyd]

The important question to ask over one of javidx9's older videos is should catmul roms and bezier curves become a part of geometry2d lib?

The work has already been done to optimize and solve the linear regression crisis, smooth interpolation for constant velocity and intersection.

My personal take:

I feel that they do from geo2ds point and line primitives deserve their own types but this feature warrants feedback from community before going out and bringing it in.

As a long time watcher of Javid's channel have got to strongly recommend in favor of these primitive types. Curves are everywhere and extremely useful for 2D games.

I support adding splines, since most implemented function checks (such as intersects, overlaps, etc.) make sense.

Agreed, I'll add some sort of placeholder for spline - we'll need some real maths experts though to start integrating them into operations with the other shapes. That said, having a robust spline primitive is useful in its own right. I'll add the basics for now.
