Add push, publish workflows

[whytro]

Adding the push and publish workflows for this project. Marked as draft, as I would like to shift the CIBW commands back to the pyproject.toml file to cut down on code duplication, but also because the PyPI details need to be finalized as well (ie. user & secret).

You could send me the password to the testing PyPI, then I add it to the secrets here.

BTW @SiarheiFedartsou how's npm handled there? ref https://github.com/Project-OSRM/osrm-backend/issues/6610#issuecomment-1686627839

Addresses #20

• I've also gone ahead and changed the package name to osrm in some of these commits, since changing the wheel name would've required a change in the __init__ folder structure anyways.

These further commits should address #14 .

The osrm executables were added as the __main__ of the osrm module. As a result, the osrm executables are accessible in the following manner:

Example for running osrm-datastore:

python -m osrm datastore <arguments>

An important thing of note is that the if(LibOSRM_FOUND) branch has an issue where the copied executables lack execute permissions.

Great work @whytro!

An important thing of note is that the if(LibOSRM_FOUND) branch has an issue where the copied executables lack execute permissions.

That's strange, it seems to say that the file(COPY ..) command preserves input permissions: https://cmake.org/cmake/help/v3.27/command/file.html#copy.

I've also tried putting in additional arguments, such as USE_SOURCE_PERMISSIONS to no avail, so I'm not entirely sure of the cause.
