Fix constraints on relationship between gauges and measurements/predictions
measure_date is the time of measurement, not date_issue.
There can be only one measurement at a time for a gauge location,
independently of gauge versions with differing validity.
The 'measure_date' of a prediction can well be beyond the validity
of the gauge, since a new gauge version might appear within the
time range of the forecast.
There can be only one prediction at a time per date of issue,
independently of gauge versions with differing validity.
