icalendar.parse - to parse and fix calendars

[niccokunzmann]

icalendar.parse can be an easy entry point to parse calendars and other components.

Currently, we have jCal and iCal as input.
Both can be a bit broken, too.

icalendar.parse should take care of the following circumstances:

• it takes a calendar in any format supported (bytes, str, path | json, ical)
• it also applies some fixes to components Cleansing of corrupted icalendar data niccokunzmann/icalendar_compatibility#3

Discussion

icalendar.Calendar.from_ical is supposed to keep the calendar intact as much as possible.
This function alters the calendar and applies known fixes. (deduplication for example)
