AWB Emsland request this AND next years data instead of only next years

[niklasdoerfler]

This PR tries to fix #3131 by adding a new (optional) parameter, in which the corresponding request period can be entered to override the default request period.

Therefore, for the specific issue, you can enter "Jahresübersicht 2024" to get the waste collection schedule for the current year.

If it's always Jahresübersicht {YEAR} I think it is better to set this in the code instead of the user. In your approach, the user needs to change the config regularly. I think the best way to approach this is to rename the fetch method to get_collections(self, year: int) -> List[Collections) and set the year according to the parameter and use a new fetch method like this:

def fetch(self) -> List[Collections]:
  now = datetime.now()
  entries = self.get_collections(now.year)
  if now.month != 12:
    return entries
  try:
    return entries + self.get_collections(now.year + 1)
  except Exception:
    return entries

I agree, that's a good point! That's why I've now tried a different approach, where I first query all available years and then retrieve the corresponding iCals and merge them all.

Thanks for your contribution. I like this approach
