Simplify some outlines

[Finii]

[why]
The SVG contains groups of paths that were obviously differently colored before resulting in a glyph with very strange outlines.

[how]
Flatten all path to one path.
Simplify the path.
Hand-optimize some points and remove others.
Double points and very sharp tips.

From 511 points to 176.

Examining the other big file sized icons...

OH MY

314 to 29 points in 3 seconds 😒

10k -> 1k

And this:

218 to 95 points...
16k -> 3.2k

The next in size (raspberry) is already as optimized as possible, point wise:

Sorry I did not mean to ping Lukas specifically...

The icons looks the same, LGTM

Thank you for reviewing :-)

Did similar things here

• original: Fix spurious path in Pug icon ryanoasis/nerd-fonts#1542
• original: Fix spurious path in Livescript and R ryanoasis/nerd-fonts#1543

Hope most of the really bad things are now fixed. Well, one PR is pending at MaterialDesign, and Codicons also had two broken glyphs. Do you think we should update Codicons? But then a lot icons changed dramatically to some more modern version. Sigh.

Mmm, seems last update was about 3 years ago, could be that some users are expecting to have the same exact icons as in VSCode.

Also the fact that are some "missing" icons (could be instances in other font sets), there are 387 nf-cod-* icons on NF but 457 on https://github.com/microsoft/vscode-codicons/tree/main/src/icons with 35 changes last year.

Maybe is worth a discussion on NF. Personally I won't oppose to the change because pretty much all the icons for code that arrive to my terminal it's because I'm using fancy plugins on Neovim & other applications, so the maintainers of such plugins are the ones who really control which icons to use, at the end I'm just a final user that uses whatever arrives from upstream.

Thanks for your thoughts! 💚

Hmm, that does not look like so many, but I have not counted.

And I was mistaken, it was Material that has changed dramatically, the changes in codicons seem all very acceptable and I see no reason to not do it.

And all (that means 100%) of the users I talked to (n = 1) said an update would be welcome :-)
The problem is that one can not reach 'the Nerd Font users' in any meaningful manner.

I think this will go.
