Instrain

- Fix but in 1.7.2 that resulted in all 0s with parse_gene_annotations

- Update to parse_gene_annotations that spells things out on the genome level

- Bring things up-to-date and working on python 3.10
- Make profile_genes use "fork" instead of "spawn" to make it work with higher python versions (even though it's already deprecated)
- Mark specific tests to skip when samtools isn't installed
- Remove "pd.append" calls (to avoid lots of warnings)
- Make all tests work with python3.10
- Remove numba and scikit-learn as dependencies (make numba still work if it's installed)
- Lots of refactoring to get around pandas warnings

- Update help; remove deprecated things
- Added "parse_gene_annotations" method
- Added auxiliary script "recluster_instrain_compare"

- Update numpy requirement to avoid numba bug

- Fix SNP pooling bug https://github.com/MrOlm/inStrain/pull/111
