v1.2.3

DeepVariant configuration fine-tuning:

• Set unifier_config::max_alleles_per_site=32 to prevent excessive PL blowup (#201 @xunjieli).
  • Alleles exceeding this limit are "kicked out" into monoallelic rows.
• Set genotyper_config::allow_partial_data=true so that non-called reference bands don't cause non-calling of nearby variants
• Fixes several minor bugs in unifier & genotyper causing (rare) copy number discrepancies between gVCF & pVCF
