Source Name: validation_lookup_and_reformatting.py
Version: Python 3.7
Author: Grant Haynes, National Geodetic Survey, National Oceanic and Atmospheric Administration
Updates: 2021/04/30 - V.I complete
2021/05/27 - changed the default hour from 1 to 0, added max hour argument
which results in a default dt string with the maximum hour, consolidated all validation
lookup and related code to this script
Description: This script contains a class with class level functions to reformat strings
into those required by the xmls
