feat: add consensus peaks subworkflow

[kelly-sovacool]

Changes

• new module custom/consensuspeaks adopts the consensus peaks script from ASPEN.
• new subworklfow consensus_peaks is a refactor of the consensus peaks script:
  • supports optional normalization
• new modules for the consensus_peaks subworkflow:
  • cat
  • bedops/bedmap
  • bedtools: sort, merge, map
  • custom/combinepeakcounts
  • custom/normalizepeaks

dev notes

nf-core subworkflows create-test-yml fails locally, it assumes nf-core even in a custom repo (nf-core modules create-test-yml doesn't have this bug). Solution is to first commit & push the new subworkflow, then run it with the git remote specified, e.g.

PROFILE=docker nf-core subworkflows --git-remote https://github.com/CCBR/nf-modules  --branch consensus-peaks create-test-yml consensus_peaks --run-tests --force --no-prompts
