1.0.1

Changed

• An error will be raised if any audioTrackUID elements or CHNA rows have ID
  ATU_00000000, as references to these elements could be confused with silent
  audioTrackUID references.
• Miscellaneous improvements to testing infrastructure.

Fixed

• When generating BW64+ADM files (with ear-utils), do not generate
  audioTrackUIDs with ID ATU_00000000, which (as above) could be confused
  with silent audioTrackUID references.
• Updated use of attrs to fix deprecation warnings.
• Wrong imports and CHNA chunk generation in replace_axml command.
• Pytest warnings fixed by upgrading pytest-datafiles to 2.0.
• Error when testing block_aligner on python 3.7 with coverage enabled.
• Error in PeakMonitor when rendering very short files.
• dump_chna in binary mode on python 3.
• Padding character in axml chunk.
