Support for GitHub file path in link instead of inline model

[tenstad]

Would be nice to be able to link to something like https://ochafik.com/openscad2?file=https://github.com/tenstad/keyboard/blob/main/keyboard.scad, and then render the scad code at that location.

Hi @tenstad , thanks for the suggestion!

Fetching arbitrary files on the web is tricky as it requires CORS headers (which I don't think are set on github.com), or going through some proxy server.

In the meantime I could potentially add https://github.com/tenstad/keyboard (looks cool!!) to the list of bundled libraries (just added a #testpath:/libraries/keyboard.scad syntax for e2e testing of bundled files, could make it cleaner), if it's licensed under GPL2+ or compatible (e.g. Apache 2.0, MIT...). Currently all libs are loaded but I hope to make this lazier to scale to more libs.

Tried curl -v https://raw.githubusercontent.com/tenstad/keyboard/refs/heads/main/keyboard.scad and got the following, meaning it could work?

< vary: Authorization,Accept-Encoding,Origin
< access-control-allow-origin: *
< cross-origin-resource-policy: cross-origin

Anyways, added a MIT license, so feel free to bundle it regardless of this issue!

Thanks for clearing that, my confusion came from the text-only content-type header (for security reasons).

I've added a #url=... in #93 for testing purposes, but I'd need to give it a bit more love (& UI integration) before it's considered an official api.
