(yanked from PyPI)
- Update vendored pygments to 2.9.0
- Update commoncode to latest version
- Use new libmagic configuration based on a plugin, and environment variable
or the system path.
- Only do content-based detection for programing language if there is no extension.
- Remove Actionscript3 from programing language detection. This is not common
enough and is the source of too many false positives.
