Add module stainwarpy/transformsegmask

[tckumarasekara]

This PR adds,

• stainwarpy/transformsegmask

stainwarpy
modules for registration of H&E tissue images with their corresponding multiplexed images and to transform the segmentation masks of one image type to be able to use with the other type.

• As first step, stainwarpy/extractchannel extracts the alignable channel (preferably DAPI) from multiplexed image.
• As second step, stainwarpy/register registers H&E and multiplexed images and output the registered image, transformation maps and evaluation metrics for the registration performed.
• As third step, stainwarpy/transformsegmask transforms the segmentation mask of one image using the transformation maps created from the second module.

PR checklist

Closes #9703

• 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.
• Broadcast software version numbers to topic: versions - See version_topics
• 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:
  • For modules:
    • nf-core modules test <MODULE> --profile docker
    • 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
