Export Color for Calendar and Events
We can now create events with their own color, and import events with a COLOR:#...
set, but exporting does not contain the calendar nor event colors.
At least for events, this seems to be intentional: https://github.com/ProtonMail/WebClients/blob/2a9685b89d7127f29c53020d38e765b513772df4/packages/shared/lib/calendar/export/export.ts#L155
However, by not exporting this, it's effectively a lock-in / walled-garden -esque feature, so I cannot in good faith use it because I know that for now I would lose it if exporting for use elsewhere.
This should be enabled in at least the following places:
- export of a calendar should include calendar and event colors
- sharing a calendar publicly should do likewise in the .ics
