Widen HRRR profile spatial matching from 0.05° to 0.07°

Browse source 
The propagation grid stores profiles at 0.125° intervals, so contacts
up to 0.0625° from a grid point would miss with the old 0.05° tolerance.
This caused has_hrrr_profile? and find_nearest_hrrr to fail matching
against existing data, leaving contacts incorrectly stuck as pending.
