surfboard requires old version of numba

[eremingt]

According to setup.py, this is surfboard requires numba==0.48.0 because of an issue with Librosa 0.7.2 Can this requirement be relaxed with librosa 0.8.0?

I may be able to help test. Just tried extracting a few features with numba v 0.53.0 & librosa v 0.8.0 and no errors so far.

When using formants_slidingwindow, the error "input seems to be ill conditioned" is reported if numba==0.53 is used
