The XRF organization_code is incompatible with the Transmitter Code lookup table

[jasrys]

The description for the organization_code property in the XRF record arbitrarily adds and removes valid values from the Transmitter Code lookup table. e.g. it adds the values ISW and ISR and removes the values 000 and 099 from the Transmitter Code table. Should a separate table be created for this organization_code property adding and removing the relevant so that the referenced lookup table is accurate as is
