Potential support for CRAM input

[HudoGriz]

Hello ClinSV team!

Great software, we include it regular in our new workflows! We would like to re-analyse old data, but the alignments are compressed in CRAM files. We are sure that there are more labs which keep the data as CRAM (less space than BAM), so we suggest including CRAM files as optional input files.

Keep up the great work!
