v2.2.0

Improved phase set/block analysis

• vcfdist now skips unphased variants by default
• add phasing info from PS tag
• switch "errors" only counted if they occur within phase sets
• added phase set count and NG50 (inputs)
• calculated phase block NG50 (break on switches) and NGC50 (break on flips and switches)
• reorganization and variable renaming in phase.cpp

General improvements

• VCF parsing and warnings are more concise/consistent
• allow variant selection by FILTER
• truth and query variants are no longer realigned by default
• removed unnecessary data copying from sort_superclusters() which significantly improves overall runtime and fixes uncounted runtime
