Rewrite of the awk calendar filter to make it posix compliant. Tested
with awk --posix (awk -V = GNU Awk 5.1.1). Also added some improvements
to readability and formatting.
This complements commit 3ef4a3ca05 ("filters: try and make awk scripts
posix compliant").

Implement a filter to read text/calendar (ics) data with awk.
Parses multiple events and shows the date recurrence if
available. Awk alternative to the python filter.
