Proposal for a sublineage of A, sequenced in Nigeria and UK

[corneliusroemer]

There's a cluster of 4 sequences with recent circulation in the UK. It was previously identified in Nigeria.

To my knowledge this is the cluster that UKHSA called A.3 in a recent technical report. So it would make sense to give this also the official name A.3 here.
