0.12.0

Backwards Compatibility Notes

• Support for Python 3.4 has been dropped since Python 3.4 is no longer
  a supported Python version upstream. (But it will likely continue to
  work until Python 2.7 support is dropped and we port to Python 3.5+
  APIs.)

Bug Fixes

• Fix ZstdDecompressor.__init__ on 64-bit big-endian systems (#91).
• Fix memory leak in ZstdDecompressionReader.seek() (#82).

Changes

• CI transitioned to Azure Pipelines (from AppVeyor and Travis CI).
• Switched to pytest for running tests (from nose).
• Bundled zstandard library upgraded from 1.3.8 to 1.4.3.
