uid_prefix per url

[sbrunsch2024]

Hi,

implementing uid_prefix per url instead global would be more flexible.

I have Implemented in v1.4.0. This will allow you to add custom uid_prefixes. I also adjusted cleanup, so that you can selectively cleanup just that prefix via

python3 src/calendar_sync.py --cleanup HANDBALL-
