README example .gpkg layer names

[dmragar]

From the example in the README, a hydrofabric generated with:

hfsubset -w medium_range -s nextgen -v 2.1.1 -l divides,flowlines,network,nexus,forcing-weights,flowpath-attributes,model-attributes -o ./palisade.gpkg -t hl "Gages-09106150"

has names:
flowpath-attributes and flowlines, while datastream expects flowpath_attributes and flowpaths

Not sure if this is related to the hf version (2.1.1) called by hfsubset. Or perhaps fixed by changing the params to -l (not tested)

I believe this is a mismatch between t-route and the layers provided by hfsubset. t-route is looking for flowpaths and flowpath_attributes, but hfsubset is providing flowlines and flowpath-attributes. I think I noticed this same thing a few weeks back and started an issue here. @mikejohnson51 @program--
