New features

Calendar

This is a major release - adding a 'Garbage Collection' calendar to HA. This allows you to check not only the next coming collection but also check all past and future collections!
A large portion of code was refactored (and hopefully improved), it should run faster and better.
There is also a new attribute hidden if for the entities you'd like to hide from the calendar (useful for calendars included in groups, so they do not show twice).

If you would like to let me know that you like it, you can always

Move collection to next day

Changes

The entities now use custom device class, which should improve handling translations.
General stability and speed improvements. The integration is now more granular and uses async methods more.
