v0.9.1

Fixed

• CLI no longer prints an error message if finaletoolkit is called without args.
  Instead, a help statement is printed.
• frag-length-bins, when writing a file, now writes the interval between
  min and max as inclusive. That is, previously when min=1 and max=2,
  only fragments of length 1 are reported. Now when such a result is calculated,
  the interval given is min=1 and max=1.
• Updated some descriptions and docstrings.

Added

• adjust-wps now has an option -S or --exclude-savgol to not perform
  Savitsky-Golay filtering.

Changed

• Several CLI options were renamed so that underscores become hyphens. This is
  for consistency and to simplify writing commands.
