This PR permits duplicate block requests from peers if the request is "small", defined as when only the block header and justification are requested. A separate, milder reputation penalty is issued for those duplicates. This prevents peers from being banned for (e.g.) duplicate ancestor search requests, which can occur if a peer has disconnected and reconnected. This is one of the solutions discussed in #10794.
Should resolve #10794.
