Added function that queries the XML file. We just look at the first species and check for the key for NASA7 or NASA9 and error if it's not one of the two. We rely on the subsequent parsing of the thermo during the read_thermodynamic_data call to catch inconsistent/mixed use of NASA7 and NASA9. There is unit testing of both NASA7 and NASA9 cases.
Should be merged after #254.
Closes #251.
