one chunky PR to review: github.com/nf-core/sarek/pull/2349 It adds filtering to parabricks mutectcaller which required a bunch of refactoring to share the subworkflows with mutect2 (which then triggered some more refactoring to merge the two mutect2 (tumor and paired) into one)

41 files is not chunky

tests are passing woohoo
