Version 0.19.0.0 (3 June 2025)

• Add briefHangPoint modifier. This allows one to specify the command length
  after which the rendering will change from aligned with the end of the
  command name to being indented on the next line.

• Add parserOptionGroup for grouping Options together, similar to command
  groups. Requires the breaking change of adding the propGroup :: OptGroup
  field to OptProperties.
