Description

Fixes #2232 and #594

• [x] Updates API to use static interface methods for improved usability and extensibility.
• [x] Optimizes and modernizes SIMD pixel shuffle operations, adding ARM support.
• [ ] ~Optimizes and modernizes SIMD Vector4 packing operations.~ I'm leaving this for a follow up PR

I don't expect anyone to reasonably find the time to analyze this line-by-line as it's a massive piece of work. However, changes on the whole are simplistic and the developer benefit massive.

API change Elevator Pitch

The abomination that is.

TPixel pixel = default;
pixel.FromScaledVector(vector)

Becomes, as nature intended.

TPixel pixel = TPixel.FromScaledVector(vector);

All other conversion methods follow suit where applicable.

Let's merge this. It's awesome.
