Changes:
- Uses pyproject.toml instead of setup.py for installation
- update minimal requirement for ncbi_genome_download to be compatible with the last NCBI format (issue #42)
- use --amino option for mafft protein alignements in order to force sequence type to be proteic and deal with ambiguous aa (see 728445d#commitcomment-122306169)
- fix issue with protein names. They must fulfill the conditions described in https://aperrin.pages.pasteur.fr/pipeline_annotation/html-doc/usage.html#protein-files
