Rolling back repo to focus on DSP Node and SoundStream

After giving it a bit of thought today, I think I'd like to keep this as a raw DSP framework just for now. SoundStream and the DSP Node should be useful for building audio tools on top of, however before diving too deeply into the synthesis part of the lib, I need to focus a little more of my time back towards my generative framework again, as I have some deadlines fast approaching! I will definitely come back to the oscillator and synthesis implementations soon, however for now I thought it might be best to remove these WIP files to keep the repo as a neat, minimal DSP framework, rather than a half finished synthesis lib. Feel free to revert these changes back if you feel these files should remain here in the meantime, however I feel they'll probably just clutter the lib until I have some more time to flesh it out properly. Will get back to this soon!
