feat(tools/nsfv-setup): Move NSFV setup script out of //users r/1082
This program can be used for noise-cancelling in arbitrary audio streams. See CL/576 and CL/577 for more details. This moves the script out of my users folder and to //tools, and adds two changes: * Existing sinks will be removed & reinitialised * The sink is changed from stereo->mono (which seems to make little difference but is more reliable) * The parameter has changed from 50 to 42 because I felt like it Change-Id: Id9ff285fefd682ccc4d9f18e46b5fde9cd056aa7 Reviewed-on: https://cl.tvl.fyi/c/depot/+/578 Reviewed-by: glittershark <grfn@gws.fyi>
