Btyper3

Added
- Added "*Bacillus pretiosus*" (NCBI RefSeq Assembly Accession GCF_025916425.1) to the `--ani_typestrains` database
Changed
- Changed `--ani_typestrains` to `True` by default (to be compatible with BRisk USDA project)

Fixed
- `btyper3.ani` occasionally crashing in `--ani_geneflow` when the best hit is under threshold and not enough hits were obtained.
Changed
- Reorganize `btyper3.ani` data files to store metadata and rewrite formatting code in `Ani.run_fastani`.

Fixed
- `btyper3.ani` failing to read query genome from an exhausted sequence iterator.

Fixed
- PyFastANI result handling code crashing on genomes too distant from the database genomes.
Added
- Warning when running `btyper3` on a very fragmented genome.

Fixed
- Issue with PyFastANI migration when running the `--ani_geneflow` and `--ani_typestrains` operations.
- Wrong program name being shown when running `btyper3` in module form (`python -m btyper3`).

Added
- Added "*Bacillus arachidis*" (NCBI RefSeq Assembly Accession GCF_017498775.1) to the `--ani_typestrains` database
- Added *Bacillus rhizoplanae* (NCBI RefSeq Assembly Accession GCF_917563915.1) to the `--ani_typestrains` and `--ani_species` databases
Changed
- Changed the name of "Unknown Species 17" to "*Bacillus arachidis*" in the `--ani_species` database
- Included `ndb`, `not`, `ntf`, and `nto` in the list of BLAST database files to delete
