The fifth release of the 0.3 series.
Minor changes:
- Now we do not support Python 3.6 and Python 3.7 because of NumPy and SciPy dependency.
- Instead of previous Python versions, we are now supporting Python 3.9 and Python 3.10 officially.
- Implement HPSS function in the package, so now we do not need librosa.
- Now we use GitHub Actions for testing codes.
