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
