Lots of cleanup required.
Still need to piece it all together.
EXTREMELY rough, so much cleanup to do from debugging issues.

Also stretches the type to avoid possible overflow.

Does lossless image decoding for WebP images.
It worked on all the lossless images I tried, so as best as I can tell it works.
Definitely scope for optimisations and there's probably too much type conversion going on but the lossless does a lot of indexing with random numbers.
Feedback would be appreciated.
