[IATI] Use new codes from OECD update

[stevieflow]

Following the completion of the update to IATI code lists from this notice, CoVE will need to refresh its own codelists

[Bjwebb]

Do you have a sample file handy that needs the new codelists to validate?

[stevieflow]

@Bjwebb yes, I created an XML here: IATI/validator-web#1004 (comment)

Thanks
