writing nc file with different frequency (Update for #697)

A code added in LowerColorado_TX_v4 for running the bmi. It uses the "test_AnA_V4_HYFeature" yaml file.

Additions

make sure in test_AnA_V4_HYFeature.yaml file lastobs_output_folder commented out ( : #lastobs/)
The flowveldepth functions added to model_DAforcing file.
LOG also added instead of print (using log_level_set function)
waterbodies_df was giving error in reconstructing the dataframe that some column are missing. I add the 3 columns of 'lon', 'lat', 'crs' and after reconstructing the dataframe drped them.
flowveldepth function added
run_with_BMI.py file is updated on the base_path address to be independent of my directory.
output_parameters added in the troute_model file
Config file edited in a way that a validator checks if 'nts' is a valid value
