Move external licenses to separate directory

[charliermarsh]

I received some feedback from a friend at Google that our license structure was failing to get picked up as MIT when run against the license auto-detection systems that make it easier for Google employees to contribute. This was the other structure I considered initially (add licenses to a subdirectory), so lets run with that instead.

@messense - Do you know if there's any way for Maturin to include these if I'm willing to manually enumerate them? (Even if they're not identified as "licenses" in any special way, but rather, just included in the distributed wheel in some form?)

You can use the tool.maturin.include option, see https://maturin.rs/metadata.html#add-maturin-build-options

Thank you :)

I'm finding that I have to do include = ["../licenses/*"] given our structure. Which gives me this slightly strange wheel:

Would it be too weird of me to symlink licenses into python, to get this?

@messense - Definitely not urgent, I decided to merge the licenses back into a single file (and was able to fix the broken license detector via some licensee hacks, I think).

I think it's fine for now, in the future ruff-X.Y.Z.dist-info/license_files folder is the proper place to put them. [tool.maturin.include] doesn't support changing the path in wheel/sdist at the moment.
