Template add-on for score audio effects

• Read the Avendish docs here and for more advanced use-case, plug-in docs here.
• When cloning this template for the first time, run :

./init.sh YourAddonName
git add .
git commit -am "Initialize addon"

in order to update the namespace, filenames, etc to match your name, as well as generate unique identifiers for your classes.

• Add a Github Access Token named GITHUB_TOKEN for the Github actions to work correctly (a zip file will be released when tagging a version). See .github/workflows/release.yml for more information.

• When it is ready and you want to make it available to all ossia score users, register your add-on by submitting a pull-request to https://github.com/ossia/score-addons

• Do not forget to regularly update the versions of score you are testing against by updating .github/workflows/jit.yml
