add LastObs reading and writing for command-line run of main_V04 with HYfeature hydrofabric

Currently, reading lastobs files to create lastobs Dataframe and then writing lastobs files from run_results with updated lastobs time and values from computing mc_reach.py is only available for BMI running and command-line run for NHD hydrofabric. This PR adds such capability as well for command-line run with HYfeature hydrofabric.

Additions

def _read_lastobs_file() from model_DAforcing.py to DataAssimilation.py
lastobs_output parameter under output_parameters in test_AnA_V4_HYFeatuere config file
output_parameter in input argument list of def init of class HYFeatureNetwork
if lastobs condition in output.py for activating writing lastobs files
