A few fixes

[standage]

This update introduces 3 changes.

• The copy number of reference allele k-mers (occurrence in the reference genome) is reported along with per-sample abundance of alternate allele k-mers so that the likelihood score can be re-computed/checked directly from the final VCF
• The homopolymer filter is made slightly less aggressive.
• A bug related to reporting multiple optimal calls was fixed, and a corresponding regression test was added.
