    The stop_times.txt table can be *huge*, and can eat all your RAM
    as 100MB of string data gets split into 1GB of dict data.

    Instead, load the table in chunks, and filter it for the content
    we want before loading the next chunk.

    Reducing the huge stop_times file by ~95% also has the side effect
    of cutting the script runtime in half.

    Read data from a GTFS table, map the data into a list or dict for
    easier iteration or searching or other use. Each line of the table
    is mapped into a separate subdict, with a unique key.

    Many GTFS tables include a unique value (Example: trips_id in the
    trips.txt table) that this function automatically uses as the
    dict key. If a tables has no unique key (Example: calendar_dates.txt),
    the system generates a unique key using an incrementing row counter.
