Fasttracker II clone v1.57

• macOS: Fixed problems with not being able to record/sample audio (again)
• Fixed some aliasing issues in the windowed-sinc interpolator (deltas > 1.5)
• The windpowed-sinc interpolator now has 16 points instead of 8, and double the phase precision. This should increase the audio quality, but could also make the program run slower on very low end systems (like a Pi, for example)
