Feature Request: .ics support

[cachius]

Some services provide calendar data only in iCalendar format. For example Todoist:

The Todoist calendar feed sets up a one-way sync from Todoist to any calendar app that supports calendar feed subscriptions.

For this it would be great if URLS pointing to iCalendar resources are supported.
You could designate them with the webcal:// scheme (see https://en.wikipedia.org/wiki/Webcal)

Right now you have to script this somehow.
Since ics parsing is already supported by Outlook CalDav Synchronizer this would be a great addition with little effort.

Kind regards
