"""Omnibus parser of NWS Text Data
This is intended to be a catch-all parser of text data. As it currently
stands, it does not correctly hand products off to the correct
sub-processor, but some day it will!
Args:
text (str): The actual product text, this can have the <cntr>-a
character to start the string.
utcnow (datetime, optional): What is the current time, this is useful
for when ingesting old data. Many times, the product does not contain
enough information to assign a current valid timestamp to it. So we
need to know the current timestamp to do the relative computation.
ugc_provider (dict, optional): Provides NWS UGC metadata, the dictionary
keys are UGC codes.
nwsli_provider (dict, optional): Provides NWS Location Identifiers to
allow lookup of geographic information for station identifiers.
Returns:
TextProduct: A TextProduct instance
