python3-x-wr-timezone (Handling of X-WR-TIMEZONE icalendar property)

Some calendar providers introduce the non-standard X-WR-TIMEZONE
parameter to ICS calendar files. Strict interpretations according to
RFC 5545 ignore the X-WR-TIMEZONE parameter. This causes the times
of the events to differ from those which make use of X-WR-TIMEZONE.

This module aims to bridge the gap by converting calendars using
X-WR-TIMEZONE to a strict RFC 5545 calendars. So, let's put our
heads together and solve this problem for everyone!
