Added IANA considerations for objective values.

It looks OK but I am confused. Where are the "BRSKI AN_Proxy Objective Value" and "BRSKI AN_join_registrar Objective Value" registries defined? They don't seem to be in the posted version of draft-ietf-anima-constrained-voucher. Would they be added in the BRSKI section at https://www.iana.org/assignments/brski-parameters/brski-parameters.xhtml? If so there would need to be a cross-reference from https://www.iana.org/assignments/grasp-parameters/grasp-parameters.xhtml#objective-names

OK, that seems right. Thanks!

Update: per the IETF 118 discussion, the GRASP related content was moved out from cBRSKI (= constrained-voucher) and I think this was equally proposed for constrained-join-proxy. So that would imply this PR needs to be updated/changed to reflect that.
