Update 2023 09 20

[erinyoung]

Moderate update:

• current-datasets is now set to false by default
• changed datasets download to only download new genomes (does not download genomes from list)
  • This retires params.genome_references
• updated fastani to 1.34
• since fastani now allows *.gz as input, the included genomes are now separate compressed files
  • the 'decompression' process was removed
• changed fastani_ref to accept a comma-delimited list of fasta files (or fasta.gz files) to be added to the fastani references
• added fastani_ref_list to accept a file with a on each line for fasta files (or fasta.gz files) to be added to the fastani references

Resolves #122.

More genomes can probably be added in the future.
