Description
To support dynamic updates to the UTB, the SDK should provide facilities to automatically download and cache new UTB records every time it receives from the aggregator a UC with epoch number higher than in the latest UTB record currently in the SDK's cache.
The new UTB records should be downloaded via a call to the API endpoint specified in https://github.com/unicitynetwork/aggregator-go/issues/115. Each record must be verified by checking that it has been signed by a quorum of BFT validators from the previous epoch before the record is accepted and added to the SDK's cache.

Research direction
Start by locating where the SDK receives aggregator UCs and stores the latest UTB record in its cache. Review the API endpoint described in aggregator-go issue 115, then trace how records can be downloaded and verified against a quorum of previous-epoch BFT validators. Done means newer records are fetched, validated, and cached automatically.
