[WIP] feat: simple hex data colorization

[CreeperLin]

Colorize hex data by treating each byte as an 8-bit color (3, 3, 2 bits for R, G and B). I find it useful visualizing binary data with unknown format.

Also an implementation on #279, although using RGB instead of HSL, and the alpha is currently fixed at 0.5.

If this feature is desirable, options to toggle it and change the alpha value and even palettes can be added in the future.

I would prefer a toggle option for something like this as I find it harder to read the data in some areas.

The visual experience is terrible, you need to reduce the brightness and saturation of the colors so as not to interfere with the reading of the data.

would you still work on this?
byte colorization is essential for pattern recognition and the extension really lacks that feature

the important part is the color mapping. I think just interpreting it as an 8bit color makes little sense.
This guy put together a really good color scheme (in my opinion):
