Add validation rules to PrevalenceAllLineagesByLocationHandler parameters

[flaneuse]

Within PrevalenceAllLineagesByLocationHandler, add the following validation rules:

location_id : str
window: int >= 1
other_threshold : float >= 0 & <= 1
nday_threshold : int >= 1
ndays : int >= 1
other_exclude : str
cumulative : bool
min_date: date/str (you already added a validation to throw an error if not a date format, so should be good)
max_date: date/str (you already added a validation to throw an error if not a date format, so should be good)

Note that a few of the types need to be adjusted (window, nday_threshold)
