Changed

• The module now includes the latest changes in the underlying Python module.
• The logger now supports rolling. The log file name has been changed to <command>.log. Each invocation of any command will append to its respective log file. Once a certain file size limit is exceeded, the log now rolls over to a new file with format <command>.<n>.log. A total of 5 rollover files is kept at most.
• Setting NRFUTIL_LOG_PREFIX no longer has an effect.
• The --license flag output now includes the licenses (where applicable) rather than printing a URL to the online version of the licenses.
