Write a minimal test for slicing the simplest wav file

[audreyfeldroy]

• Familiarize yourself with the very basics of pytest
• Create the file tests/test_slicer.py
• Define a test in test_slicer.py called test_audio_slicing
• In your test, create a simple wav file per https://stackoverflow.com/a/57192182/271697
• In your test, call audio_slicing() with your wav file and verify that the slices are created

If you have more experience with pytest and want to use fixtures, etc. you can, or you can just write the simplest possible test per above and we can iterate later.

mind if I pick this up?

Thanks for offering to take this one @RalphHuber. Just a friendly heads up that the API may end up changing... I woke up in the middle of the night realizing that we probably ought to look into using existing Python FFMpeg to reduce our lines of code, which @heymanpreet is just starting to look into.

No worries @audreyfeldroy, I'll push the PR soon. No worries if it's not useful in the end, was only a quick change last night.

What's the difference in using pydub vs FFMpeg? I'm not very clued up
