Update and fix depdendencies

Start a gui version

Add a wrapper around audio_backend that inits an fft for our purposes. Make fft processing generic over num::Floats

Cleanup pipewire backend

Use ds_p to generate test signals

Reorganize into a workspace

Light cleanup

Move const declarations to where they're used

Clear the top row correctly

Make clearing previous amplitude branchless

Draw to bottom row as well

Make sin sweep go from 0 to nyquist

Handle jack start/stop correctly

Fix overlap calculation when using JACK

Move feature-dependent crates behind feature toggles to reduce compile times

Fix auto-overlap calculation so that at least one fft is generated per frame

Reduce allocations in the critical path

Improve pw support, add feature toggles, major clean up and commenting.

Add pipewire support

Remove let chain so we don't have to use an experimental feature.
