Fabian Giesen 3aa1744a29 stb_image: New Paeth filter
This formulation is equivalent to the original (reference)
implementation but runs _significantly_ faster - this speeds up
the filtering portion of a Paeth-heavy 8192x8192 16-bit/channel
image by a factor of more than 2 on a Zen2 CPU.

I'm investigating doing a more thorough restructuring of this pass,
but this seems like a good first step.

Fabian Giesen 2f3b7e47fa tests: test_png_regress
I want to make some changes to the PNG loader, this is to get some
test coverage at least to make it easier not to break anything.

The two ref_results files that are "corrupt" files that stb_image
nevertheless loads without error are checksum failures; this is
by design, since stb_image does not verify checksums.
