Dropped support for Python <= 3.4 including Python 2.7.
Add a new recipe from the itertools documentation: nth_combination.
Added a few new functions that rely on new functions in the Python statistics module:
- Iterable.get_fmean (Python >= 3.8)
- Iterable.get_geometric_mean (Python >= 3.8)
- Iterable.get_harmonic_mean (Python >= 3.6)
- Iterable.get_multimode (Python >= 3.8)
- Iterable.get_quantiles (Python >= 3.8)
