Request for handling of tarred alignment files

[mestaki]

Usage: calculate_coverages.py [OPTIONS]

Options:
  -i, --input TEXT     Input: Directory of sam files (files must end in .sam).
                       [required]

It would be really handy if tarred folders could be provided as input. A good case point is in barnacle you could then simply point to the alignment tar in qmount instead of having to extract them first somewhere else first. These can be pretty large files after all.
