Pull request

NOTE: This is not a typical PR. Instead this PR acts as documentation on the goal as well as the changes made in this branch.

Please add a clear description of what the PR is about:

Goal: Refactor quac v1.8 to use it with bam and vcf files for rat samples created using parabricks.

Changes made (may not be complete):

• verifybamID and somalier ancestry tasks were turned off.
• For somalier relatedness, we created sites data for somalier as described here - https://github.com/uab-cgds-worthey/masala_cafe/pull/4. We tested with sites vcf created using AF from 25 to 150, and they all appeared work well at the least to identify sample identity between tumor and normal samples. Hard to comment ATM on reliability of other relatedness predictions.
