Main Changes

For license reasons, all LGPL licensed modules were split into a separate library, DaisySP-LGPL which will be under the LGPL license.
DaisySP will remain under the MIT License.
If you want to continue using the LGPL modules in your user app, you must add USE_DAISYSP_LGPL=1 to your Makefile.
The build process was not modified at all from a user perspective, when you build DaisySP, make will automatically build DaisySP-LGPL if it is present. This also applies to the use of the VS Code tasks.
The process for using modules has not changed either, simply #include "daisysp.h" as before and use the modules across both repos seamlessly.
Also created a new module called OnePole ported from pichenettes' stmlib/dsp/filter.h.
- This was necessary in order to replace the Tone filter in KarplusString without using LGPL code in the MIT codebase. Plus it's a nice module to have around.
We've gone through and upated DaisyExamples as well to reflect these changes

Tech Details

DaisySP-LGPL is compiled to its own .a file, so it can be statically linked later alongside DaisySP.
In keeping with LGPL practice, DaisySP-LGPL includes a script with instructions to create a folder with everything users need to re-link their firmware with a modified version of DaisySP-LGPL.
All modules in each repo gained a license header, which we will continue to use going forward.
