Codoff

- Restructure codoff to allow for usage as a Python library. API documented on wiki at: https://github.com/Kalan-Lab/codoff/wiki/API-and-usage-of-main-functions-in-Python-programs
- Introduce `antismash_codoff` for running codoff in batch for all BGC regions determined by antiSMASH for a single genome.
- Improve preliminary checking of input arguments/files.

**Full Changelog**: https://github.com/Kalan-Lab/codoff/compare/v1.1.8...v1.2.0

- push version in TOML
- Note to users: essentially v1.1.0 to v1.1.8 are identical in terms of functionality - just experimenting with workflows for automated upload to pypi

- Add support for additional input types including just a genome in FASTA format with a focal region defined using coordinates. pyrodigal is used in this case to perform gene calling.
- Improve output clarity
- Add argument for producing plot of simulated cosine distances with a marker for actual focal region cosine distnace
- Make empirical P-value computation always on
