HLA typing

hlacaller – Perform identification of highly polymorphic HLAs with human build 38 (hg38). The recommended option is optitype, using the OptiType caller. Also supports using the bwa HLA typing implementation with bwakit For typing either with optitype or with bwakit, aligner must be set to bwa.

aligner: false + hlacaller: optitype in the template yaml gives a warning whan attempting to create a project yaml, and errors out when running bcbio, issue 3252.
