Version 0.5.1

This is a bugfix release.

Version 0.5.0

- Breaking change: remove some parameters to simplify reader mode selection; see
  sllurp#114 for details.
- Improvements to Impinj extensions, including temperature measurement support
  and fixed-frequency support for Impinj readers in supported regions
- Tag filtering based on EPC prefix
- Unique ID per sent message
- Better Python 3 support (now fully works, but some 2.7-isms may remain in the code)
- Miscellaneous bug fixes, linting, and unit tests
