Pd / Heavy changes

Enzien audio, the team behind Heavy (the Pure Data compiler we use) are rolling out an API change today.
This will likely break the Pd compilation stage both online and using OwlProgram until we can roll out our own upgrade.
Apologies for the downtime, we’ll try to make it as swift and painless as possible.

This should all be working now!
The changes pertain to how parameters are referenced. If you notice any problems with assigning or getting parameter values let us know.
