Add package: verovio

[IsakTheHacker]

Fixes #462

[IsakTheHacker]

To build verovio, you need to have swig installed!

Thanks; in that case, please add a comment to the meta.yaml file giving instructions for installing swig.

Also, to add a new package, we need a test script to verify that it works. Please do the following:

• Follow the instructions in "Testing a package" in the README.
• Push your test script to this PR.
• Post a comment saying which Python versions and ABIs you have tested.

I have added an instruction on how to install swig and I have started writing a test. When I run the app it crashes with:

Changing to draft until tests are passing.
