Restrander

[julietmWM]

Adding Restrander to the nanoseq pipeline for cDNA read orientation. This is documented in a GH ticket here.

Changes made to add Restrander to the nanoseq pipeline:

• Added a Restrander module.
• Added code to the nanoseq workflow to include the use of Restrander.
• Updated modules and subworkflows downstream of Restrander to account for the inclusion of Restrander-related information in the channel.
• Updated the check_samplesheet python file to account for the inclusion of the restrander_config column in the sample sheet.
• Updated the usage and output docs to include information about Restrander.

Have tested the updated code under the following conditions and the pipeline ran successfully:

• Run with cDNA and a Restrander config - ran normal cDNA workflow with addition of Restrander execution
• Run with cDNA but no Restrander config - ran normal cDNA workflow and did not execute Restrander
• Run with DNA - ran normally
• Run with cDNA and mix of samples with and without Restrander configs - only ran Restrander for the files with configs present

Hi @julietmWM,

It looks like this pull-request is has been made against the watchmaker-genomics/nanoseq master branch.
The master branch on nf-core repositories should always contain code from the latest release.
Because of this, PRs to master are only allowed if they come from the watchmaker-genomics/nanoseq dev branch.

You do not need to close this PR, you can change the target branch to dev by clicking the "Edit" button at the top of this page.
Note that even after this, the test will continue to show as failing until you push a new commit.

Thanks again for your contribution!
