Water Quality Data Processor

This script fetches water quality data from the Beach Watch website, processes it, and then writes it into an InfluxDB database. The data spans from the year 2000 to the current year, though it can also fetch data for specific years. The script can be run with a "first-pass" argument which causes it to fetch and process data for all years since 2000.
