Support for sdists in pixi

[tdejager]

Finally, the PR that adds sdist support for pixi. This is still in draft until I add some tests for it, I had a previous branch where I did this, so will need to move these back. Will get to this on monday.

For now you can try, pixd is my alias for a local build of pixi:

pixd init .
pixd add python
pixd --pypyi helium #helium is source only release

This works on my machine 🤞 sdist should also work, in the test I will make it so you can explicitely enable only sdists but I do not want this user-facing.

Give it a go!

Fixes: #628

Before merging, I found that it never satisfies the lock. I'll investigate now.

Edit:
Issue is:

INFO pixi::lock_file::satisfiability: failed to find a locked package for 'urllib3[socks] >=1.26, <3', assuming the lock file is out of date.

Edit2:
Urllib3 seems to include the socks but I think there is no way to check for the [socks] part? (just guessing at this point)
Maybe because it sees it uses the conda package.
