[FEATURE] SPM integration and API for DAW integrations etc.

[samirsd]

I would like to have this available as a swift package with an API that can be used to process raw audio from audio applications. For instance if I were building a DAW and wanted to have first party audio processing tools, this would be quite handy. That would be ideal, but I would be satisfied with guidance on how to integrate this directly into a native swift app.
