0.6.6

Added

• Improved help messages for substudy transcribe.
• transcribe now supports --expected-text, which should be used when you
  believe that you have a more-or-less complete and accurate transcription
  already, which you wish to synchronize. This is especially useful for songs,
  where lyrics are readily available but the error rate may be higher. This
  mode also preserves line breaks.
• The transcribe --example-text option is now --related-text, in order to
  make the meaning clearer. The old option is still supported.
• transcribe now supports an optional --lang argument. This is most useful
  when the language is known, but the available "related text" is non-existant
  or extremely short. Normally, the language is detected automatically.
