Comply with PEP 625

[friendlyanon]

PEP 625 requires that source distributions (e.g. cmake-init-0.41.1.tar.gz) contain the normalized project name (cmake_init).

Happy to take this

[friendlyanon]

You can find the PyPi build files in the package directory. The wheel already has the required name, it's just the source package that doesn't have it for some reason.

@friendlyanon Made the PR: #134

Will run a bit of testing tomorrow to make sure it works properly

@friendlyanon Tested the change - getting name cmake_init-0.41.1.tar.gz

Look working to me. Any comments or should we merge?
