Added info to pa_sensors.json for 3 S Lawndale files
Nomenclature issues on "sensor name" - not all sensors have a location of a cross street - rename json header?
Approved PR since there were additions and no deletions.
Issues faced:
ValueError: Expected object or value on 1.1-purpleair-data-extraction while trying to read in using sensor_df = pd.read_json("data/pa_sensors.json")
ImportError: cannot import name 'PURPLE_AIR_KEY' from 'src.config' (/Users/rahulgoel/Air-Quality/src/config.py) - assuming I need to set this up locally by editing the .file?
