Implements switchable color vision deficiency simulation to the docs

[aafkegros]

As discussed in #96
This implementation makes the docs require all 4 cvd type datasets implemented (normal/full vision, protan, deutan and tritan at 100% severity), and converts colors before calculating perceptual lightness, RGB/HSV values.
Colors are clipped to correct RGB codes (no negative or >255 values allowed), which allow for easy checking of linearity and other features of colormaps for the different cvd types.

I added a radio button with icons at the top to try to fit within the style the docs had until now visually.

closes #96

I found currently the plots only show up if you refresh the page, so i'll still look into that 😅

[aafkegros]

Okay i fixed the typing issues, rebased and it seems functional on my end:

What do you think?
Also: should there be an explanation of this feature anywhere?

I think this is freaking awesome. Thank you!

I'm happy to hit merge as is. It's very nicely implemented too.

• Also: should there be an explanation of this feature anywhere? I can indeed imagine maybe a little question icon right aligned next to the radio buttons that pops up a modal explaining how calculations were made, and what it's doing
• I also find myself wanting (at least) the sine-ramp image just above the radio buttons to also update... but I know that requires more stuff on our end and it should come in a follow up PR

[tlambert03]

pre-commit issues are on main too. Don't worry about them. Let me know if you want to do anything else in this PR if if it's ready for merge

[aafkegros]

This is ready to merge i think!

I couldn't very quickly find a way to implement the question icon. This would indeed probably be the best way to implement this - other option is to just add some text to the index.md but this is a bit docs-specific and not about the library itself.
I might still tinker with it in the future, but also the explanation is not essential as it is fairly straightforward as this is the commonly accepted cvd simulation algorithm.

For the sine-ramp it makes sense yes, and i indeed didnt touch it because it seemed like too much hassle, and because i personally also mostly care about the perceptual lightness 😊

[tlambert03]

Absolutely.

Thanks again for your efforts on this! Much appreciated, great addition.

Wow, seriously cool. Nice work @oanegros !
