Bug: usgs_bulk_fetch.py returns empty values

[sumabattula]

Scripts/usgs_bulk_fetch.py created files with streamflow missing data in Scripts/usgs_retrieval_logs instead of data_cache_directory specified in configs/usgsguagekrig.yaml as data/usgskrig/usgs_retrieval_logs

[sumabattula]

Replacing with get_dv still gives a lot of missing values with approx 1000 sites returning streamflow values.
Instead running Scripts/usgs_dump_raw.py and Scripts/usgs_raw_to_daily_kv.py returns streamflow from approx 6000 sites.
