Closes #766

• This comment contains a description of changes (with reason).
• If you've fixed a bug or added code that should be tested, add tests!
• If you've added a new tool - have you followed the module conventions in the contribution docs
• If necessary, include test data in your PR.
• Remove all TODO statements.
• Emit the versions.yml file.
• Follow the naming conventions.
• Follow the parameters requirements.
• Follow the input/output options guidelines.
• Add a resource label
• Use BioConda and BioContainers if possible to fulfil software requirements.
• Ensure that the test works with either Docker / Singularity. Conda CI tests can be quite flaky:
  • PROFILE=docker pytest --tag <MODULE> --symlink --keep-workflow-wd
  • PROFILE=singularity pytest --tag <MODULE> --symlink --keep-workflow-wd
  • PROFILE=conda pytest --tag <MODULE> --symlink --keep-workflow-wd

This PR adds a module for mashtree. Mashtree allows different inputs (FASTA, FASTQ, Genbank, Mash sketches) so I just called them seqs. If there is a better variable name please let me know.
