Do not require identical values when searching for a main value E.g. a value obtained using WQ.getRawValue() is not necessarily numerically identical, but nevertheless to be considered equal, to a matching Q main value. Fixes wrong descriptions in the result of a water level calculation, where not finding a matching main value led to the value being used as description instead of the name of the matching main value.
