    Return and array of FIPS6 codes which identify the county regions 
    effected by the weather alert.

    FIPS6 is a code which uniquely identifies counties in the United States. 
    For more info: https://en.wikipedia.org/wiki/FIPS_county_code

    FIPS returned by NWS alerts can be formatted two ways:
    
    Multiple FIPS per <value> block delimited by space:
    <value>066010 069100 069110 069120</value>
    
    Single FIPS:
    <value>066010</value>
    
    Note: the leading zero will be removed, as FIPS should be 5 digits
