add flbass as submodule (example)

[cleary]

I know the decision hasn't been made yet, but for the sake of testing here's a submodule example

Adding a new a submodule:

bernie@jobim:~/source/Clean-Samples$ git submodule add https://github.com/cleary/samples-flbass.git

Clone Command needs to change (and should be updated in the README:

git clone --recurse-submodules https://github.com/tidalcycles/Clean-Samples.git

To update all submodules in the repo, use:

git submodule update --remote [--merge]

To update a specific submodule in the repo, it's possible but I haven't done it myself explicitly: https://stackoverflow.com/a/45251405/3164018
