build: put python source in src/mt2 to avoid import confusion

[lgray]

Fixes more little issues that came up in #55.

This makes it so cibuildwheel automatically checks that the wheel is correctly formed and installs correctly.

Yep, there we go.
@tpgillam good to go now with a small organizational change.

@henryiii what's the correct invocation to pick up the mt2 package in this case? If I try include = ["src/mt2*"] then it fails when running tests from actions inside the uv sync venv.

I can reproduce this on my laptop but it's not exactly clear what's going wrong.

[lgray]

Ah, nevermind. Read the manual. :-)

@tpgillam I'm happy to back out the second commit I've added. It makes the extension _mt2 a sub-package of mt2, which is a common practice. It has an added side effect that the built shared object libraries stay within the package subdirectory wherever mt2 is installed, which is pleasantly clean.

Thanks @lgray ! Looks good - can you have a look at lgray#2 please? It's a "review" into this branch with a few other teaks, and bumping the version to 1.2.2 .
