For testing the z_b_PrecipitationData_GIOVANNI.py script.

1. Run z_b_PrecipitationData_GIOVANNI.py and the Weather.csv file will be updated to contain the Giovanni precipitation.
2. To reset the test, copy the content of Weather.NOAAPrecipitation.csv into Weather.csv, or copy and rename Weather.NOAAPrecipitation.csv as Weather.csv

Files:
g4.areaAvgTimeSeries.GPM_3IMERGHH_07_precipitation.20220101-20221231.12E_42N_12E_42N.csv - Giovanni downloaded data
Weather.NOAAPrecipitation.csv - Weather.csv with original NOAA precipitation data, all zeros
Weather.GiovanniPrecipitation.csv - Weather.csv with Giovanni precipitation replacing NOAA precipitation
Weather.csv - before running the test, this should contain the same data as Weather.NOAAPrecipitation.csv
Weather.csv - after running the test, this should contain the same data as Weather.GiovanniPrecipitation.csv
