support audio formats

GitHub Issue: (link)

• Meta-Issue: Audio Derivatives documentation#930

What does this Pull Request do?

This PR adds configuration to enable creation of audio derivative files using Homarus/ffmpeg.

How should this be tested?

• claw-playbook vagrant up with this PR: homarus config syntax, audio formats islandora-deprecated/ansible-role-crayfish#18

The easiest way to test this component alone would be to replace the following with the ones in the PR.

• Homarus/src/Controller/HomarusController.php

Create an audio file in Fedora. Then issue the following curl command:

curl -H "Authorization: Bearer islandora" -H "Accept: audio/mpeg" -H "X-Islandora-Args: -codec:a libmp3lame -q:a 5" -H "Apix-Ldp-Resource:http://localhost:8080/fcrepo/rest/2019-02/input3.wav" http://localhost:8000/homarus/convert --output output.mp3
