Adds support for waste event start and endtime

[sander1988]

The MR adds (optional) support for waste event start and endtime.

My local regulations say that I'm allowed to put the waste out between 20:00 (the day before collection) and 18:00 (on collection day). This way the state of the waste calendar in HA is only 'on' when it's allowed.

In my case the configuration looks like this:

waste_collection_schedule:
  sources:
    - name: ximmio_nl
      args:
        company: xxxx
        post_code: xxxx
        house_number: 1
      customize:
        - type: PAPER
          alias: Papier
          start_hour: -4
          end_hour: 18
        - type: GREEN
          alias: GFT
          start_hour: -4
          end_hour: 18
        - type: PACKAGES
          alias: Plastic
          start_hour: -4
          end_hour: 18
        - type: RESIDUAL
          alias: Restafval
          start_hour: -4
          end_hour: 18

Please provide some documentation in doc/installation.md

@mampfes what do you think about this?

Sorry, I wouldn't merge this PR. I'm afraid that this hasn't been fully thought through. And I think there are other ways to do, for example, automations for all-day events in the calendar.

Yes, but let me know if you want to merge it or not before I put in the effort.

The reason to implement it in the plugin instead of the automation/calendar is simple... Here it has to be implemented in one single place. Otherwise it has to be implemented several times for every component and automation using this feature with multiple locations of the same configuration (like hour offsets).
