Cannot create multi-day all-day events

[glynternet]

It would be great to be able to create multi-day all-day events; let me know if I'm mistaken and there is already a way to do this.

The following yaml

events:
  - summary: Single-day all-day event
    begin: 2025-01-01
  - summary: Multi-day all-day event (Jan 1st and 2nd)
    begin: 2025-01-01
    end: 2025-01-03

creates

BEGIN:VCALENDAR

PRODID:ics.py 0.8.0-dev0 - http://git.io/lLljaA

When I created a multi-day all-day event in google calendar and exported it, the fields were

DTSTART;VALUE=DATE:20250101
DTEND;VALUE=DATE:20250103

It looks like we'd need a change to the code around here to hand when both begin and end are both dates rather than timestamps, or something like that?
