WIP improvements made so far in the gif encoder. All the time/memory usage is in the OctreeQuantizer.cs I don't know what quantizer System.Drawing uses (Most likely a fixed palette with pre-dithering) but the quality difference is incomparable.

It'll probably take a better mind than mine to bring the memory usage in the quantizer down further.

P.S ArrayPool<T> rocks!!!

// How do I get these two sets of methods to return the same output value?

void Main()
{
	uint x1 = PackUint(0.5f, 1, 0.5f, 1);
	byte[] b1 = ToBytes(x1);
	x1.Dump(); // 4286644096
	b1.Dump(); // 128, 255, 128, 255 RIGHT! :)

	ulong x2 = PackUlong(0.5f, 1, 0.5f, 1);
