Missing weights

[JordanLaserGit]

hfsubset is returning a geopackage that contains catchments without weights. Should an error be thrown when the user requests weights, but none exist for some catchments within the subset?

Reproduce with:

./hfsubset -w medium_range -s nextgen -v 2.1.1 -l divides,flowlines,network,nexus,forcing-weights,flowpath-attributes,model-attributes -o ./PICT2_weights.gpkg -t hl "Gages-08101000"

Inspecting the contents of the geopackage reveal an empty list for the weights associated with catchment cat-2411779.
