Windows compatibility for paths in the tests module

[legaultmarc]

I think we will run into path compatibility problem when using:

        data_filename = resource_filename(
            __name__,
            "data/regression_sim.txt.bz2",
        )

in the tests module. We should rewrite those bits to:

        data_filename = resource_filename(
            __name__,
            os.path.join("data", "regression_sim.txt.bz2"),
        )

I am not sure if we were going for Windows compatibility in the first place...

The main pipeline does not support Windows, since this operating system is not supported by SHAPEIT (phasing tool).

Nevertheless, we might fix this for a future release in case SHAPEIT releases a Windows version. Also, it might be interesting to support Windows for the companion tools (e.g. imputed-stats).
