LYGIA Shader Library Files

This is probably the biggest version release yet and is mostly thanks to the amazing work of @shadielhajj! Thank you for doing a deep re-architecture of the PBR model and Raymarching pipeline!

Also thanks to @vade for starting the Metal translation and implementing a better color blending set of functions that account for alpha values.

Lastly thank you @sdedovic and @josephreisinger for advancing the translation to WGSL.
