QOI in Luau

A QOI image de-/encoder for fast and lossless compression in Luau, for Roblox.

NOTE: This program utilizes Roblox's beta feature EditableImage, meaning that this cannot be used by published games for the meantime.

Why?

• This de-/encoder is stupidly simple yet elegant, as it can compress images down from 50-20% of it's original size and decompress losslessly.
• Encodes and decodes in less that a second (for images less than 1024 by 1024).
• Useful for saving the data of large EditableImages in DataStores.

I can't actually make comparisions of anykind to stb_image nor PNG, as there are no possible ways of benchmarking against the other algorithms within Roblox.
