[new module] Add tRNAScan-SE module

[prototaxites]

Adds module for tRNAScan-SE.

In local testing, I was having a problem where when running in a Singularity container, the default internal /tmp space would fill up very quickly on large genomes and the program would fail due to lack of disk space. I implemented a solution that moves the working directory from /tmp to the nextflow work dir, but this requires modifying an internal configuration file. Open to better solutions, but this one was working for me.

Closes #XXX

• [x] This comment contains a description of changes (with reason).
• [x] If you've fixed a bug or added code that should be tested, add tests!
• [x] 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.
• [x] Remove all TODO statements.
• [x] Emit the versions.yml file.
• [x] Follow the naming conventions.
• [x] Follow the parameters requirements.
• [x] Follow the input/output options guidelines.
• [x] Add a resource label
• [x] 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:
  • For modules:
    • [x] nf-core modules test <MODULE> --profile docker
    • [x] nf-core modules test <MODULE> --profile singularity
    • [ ] nf-core modules test <MODULE> --profile conda
  • For subworkflows:
    • [ ] nf-core subworkflows test <SUBWORKFLOW> --profile docker
    • [ ] nf-core subworkflows test <SUBWORKFLOW> --profile singularity
    • [ ] nf-core subworkflows test <SUBWORKFLOW> --profile conda
