v4.0.0

Features

• v4 release (711ad95)

BREAKING CHANGES

• all TSV result headers are now PascalCase.
  --split-by-rg is now the default for strandedness and endedness.
  Percentages are now returned when 'Pct' is used in the header.
  strandedness now adds an overall entry when --split-by-rg.
  Read Groups are compared in the header definition and those found while
  sampling sequences. Discrepancies between the two are logged as an
  error. Header RGs without sequences are added as ZERO results to the
  output.
  endedness no longer exits with an ERROR on Unknown cases.
