feat(catwalk): use ril with pure rust webp feature

[nekowinston]

Closes catppuccin/catwalk#5, moving all the dependencies to native Rust instead of binding to libwebp-sys.

was just testing this out and noticed it's quite a lot faster than catwalk on main:

Benchmark 1: ./catwalk-main
  Time (mean ± σ):      1.216 s ±  0.010 s    [User: 1.180 s, System: 0.034 s]
  Range (min … max):    1.193 s …  1.231 s    10 runs

Benchmark 2: ./catwalk-winston
  Time (mean ± σ):     405.3 ms ±   5.7 ms    [User: 370.4 ms, System: 34.9 ms]
  Range (min … max):   396.7 ms … 418.2 ms    10 runs

Summary
  ./catwalk-winston ran
    3.00 ± 0.05 times faster than ./catwalk-main

nice!

I'd like to update this PR with my latest changes on my ril PR, but I don't have write permissions to this branch anymore.

was just testing this out and noticed it's quite a lot faster than catwalk on main:

I can pretty much replicate these results 1:1 on my own x86_64 hardware, but it seems like the compression factor is worse?

Here I'm using the PR version of catwalk to generate preview.webp in the VSCode port, preview-before.webp is the current version, and then I reencode it with ImageMagick's convert. The hexyl commands are just to verify that they're all VP8L, so correctly being saved as lossless.
The ImageMagick version has the smallest resulting size, catwalk with this PR encodes images in a way that's usually 2-3x larger than the main branch. 🤔

that is interesting, i didn't think to check file size.

i get similar results with imagemagick coming out on top:

296K    preview-magick.webp
304K    preview-cwebp.webp
304K    preview-main.webp
628K    preview-feat-ril-webp.webp
