Reaccumulate and virtual stations
When using the 1D interpolation reaccumulate with virtual stations within Snowpack, we end up with grossly wrong results: if vstations_refresh_rate = 3600 and Snowpack Meteo_step = 900, since the virtual stations in effect do two passes, there is no way to get the proper precipitation (in the first pass, it should reaccumulate on 3600s while in the second it should reaccumulate on 900s).
One solution would be to force reaccumulate to vstations_refresh_rate in the first pass.
