Idea: asking and answering FREE/BUSY time requests

[niccokunzmann]

A "VFREEBUSY" calendar component is a grouping of
component properties that represents either a request for free or
busy time information, a reply to a request for free or busy time
information, or a published set of busy time information. - RFC 5545

This library can be used to answer these requests.

To solve this:

• create tests
• create a new function recurring_ical_events.to_freebusy(Iterator[Component]) -> icalendar.Calendar - test-driven
• create a new function recurring_ical_events.of(a_calendar).answer_free_busy(arg, end=None) where arg is
  • a date
  • a start + an end
  • a icalendar.Calendar with VFREEBUSY inside
    • also respect the ORGANIZER attributes and such
• open an issue in ics-query to integrate the functionality

I am not planning on doing this.
