Modified - SelectVariants: Hook up to VariantContextUtils to recalculate AC/AF/AN, which uses the accessor in VariantContext to do this. Somehow sites that were selected down to hom-ref genotypes only wound up getting positive AC.
**IMPORTANT** I kind of need input here. The header of a file used for an integration test specifies AC as being an integer. Recalculating it casts it into an integer list (which it should be, as it allows for alternate alleles). However this appears to clash with what the jexl expression is looking for? For now, the integration test itself needed to be changed -- it's unclear what to do when the header specifies AC of being one class, but recalculating it casts to another class, and I'm not sure what to do.
I'm committing my omni_qc pipeline because I'm almost certain 2 months down the road I'm going to wonder what the heck I did to generate my results.
