Create FAPI1-Advanced Final certification tests
We need to create new tests that test the final version of the FAPI tests as per:
https://openid.net/2021/03/12/fapi-1-0-part-1-and-part-2-are-now-final-specifications/
A hopefully correct list of the changes is here:
https://bitbucket.org/openid/fapi/src/master/FAPI_1.0/changes-between-id2-and-final.md
We should follow the naming conventions agreed with the FAPI WG here:
https://bitbucket.org/openid/fapi/issues/362/language-to-use-on-the-certification-pages
The FAPIRWID2 versions of the tests need to be retained & maintained for some time - my guess is for at least a year.
