Package for Pypi

[ilesinge]

Implements #5

[ffont]

Hi @Bomme @ilesinge , I was to merge that and go ahead with publishing but the workflow for testing the package fails. I tried to fix but I'm a bit confused. Sorry I don't have a lot of experience publishing in pypi, but:

• The error seems to be related to packages = [{include = "freesound.py"}] not doing its job as it tries also to add the other files (the example and download_bookmarks_example).
• If we're not using poetry now, why are there references to poetry in pyproject.otml? Is this something to be fixed?

Thanks for your help!
