deeptools 3.5.6 update and snapshots

[pauldrinn]

Also completes #9685. Tested on different machines with docker, singularity and conda.

PR checklist

• This comment contains a description of changes (with reason).
• Ensure that the test works with either Docker / Singularity. Conda CI tests can be quite flaky:
  • For modules:
    • nf-core modules test <MODULE> --profile docker
    • nf-core modules test <MODULE> --profile singularity
    • nf-core modules test <MODULE> --profile conda

This is fine to go.
It would be helpful if the modules were swapped to use the topic channel for the version output, the details are here: https://nf-co.re/docs/tutorials/migrate_to_topics/update_modules if you are able to spend some time doing that.

[pauldrinn]

Yes I can implement that as well

@SPPearce changed all to use topic channels, thanks for the info!

[SPPearce]

Thank you for being willing to do this too!
Some comments on simplifying the version extraction, they apply to all tools. I know you just copied the previous version command, but taking the opportunity to simplify a bit as we go through.

Also you should go to the nf-core slack and post on #github-invitations to be added to the organisation, then the tests would run automatically.

Thanks for the help! I edited everything and posted on slack to be a part of the organization. Testing now so will push one more commit.
