[Feature]: Trash due date entities for reminders

[donverse]

Requirements

Is your feature request related to a problem?

No

Describe the solution you'd like

I would like to have entities available for all five trash types which carry the number of days until an event happens (= the trash is picked up). These entity values should be updated once per day. Users could then create automations based on the values of the entities, when they become relevant.

What could then be possible:
Idea 1: create automatic reminder if trash is picked up today
Idea 2: create weekly reminder to see 'trash schedule's
Idea 3: living in a Multi-Person household, person A could mark a 'trash event' complete, if not done, person B could get notified

Automations should be user created (as details may vary), but the entities should be provided by this addon.

Describe alternatives you've considered

Complicated - calculate due date of the events myself and store in helpers. But since this addon already does 98% of what I am looking for, I'd appreciate an enhancement.
