Bumps lz4 from 2.1.10 to 3.0.2.

Release notes

Sourced from lz4's releases.

Remove dead code

This release removes py3c from the codebase and strips out unused Python 2 support code. No functional changes are included with this release.

Fix OSX wheel publishing

This release fixes an issue that prevented the OSX wheels from being published to PyPi, and contains no functional changes.

Drop Python 2 support, add streams bindings, improve frame performance

This release:

• Drops support for Python 2 (although some dead code remains for future removal)
• Adds streams support thanks to the hard work of @tSed
• Fixes a performance bug with the frame bindings - thanks to @bjonen for the careful report and reproducer
• Adds Python 3.8 support

Update the bundled LZ4 library to version 1.9.1

This release updates the bundled LZ4 library to version 1.9.1.

The 2.2.x releases will be the final release that support Python 2.7. In the near future we'll begin work on the 3.0.x release which will only support Python >= 3.5, and will require LZ4 > 1.9.0.
