[ANN] OSSubprocess v0.2.0 release

I am happy to announce OSSubprocess v0.2.0. You can see the changelog here: https://github.com/marianopeck/OSSubprocess/releases/tag/v0.2.0

Such version becomes the #stable, so the installation instructions remain the same.

Note that I have improved and added more info in the documentation.

I took into account most of the feedback I received in the first release plus some other stuff from the survey.

If you have more feedback, just let me know!

Hope you enjoy.

Best,
