Support better color management (RGB profile etc) #348

Splitting from issue #270

[may belong to codecs’s repos, but Sqoosh could surface some control] Colour management behaviour is inconsistent. At times broken/dangerous. For PNGs, all input is converted to sRGB , but the sRGB chunk is not set (questionable, although browsers got better at assuming sRGB). For JPGs, RGB profiles are converted, while CMYK ones are a problem, again output is, at times, in sRGB, but there is not profile embedded.

A temporary solution for anyone having this issue is to use Sharp with:

const correctColorSpaceBuffer = await sharp(arraybuffer).toColorspace("srgb").toBuffer()
