not subsetting on TIME in default profile, already done with geoserver requet

Fix for #53.

Sneaky bug. Some gogoduck core modifications required for this fix.

Basically we will not have `-d TIME` in the ncks command, but we also don't really need it. This is because the correct time constraint is already downloaded from geoserver. All that we need to subset on is the lat/lon parameters.
