checkpoint build time Add a new optional `lastBlockDurationMs` config field to SequencerConfig. When set and less than blockDurationMs, the last block in a multi-block slot gets a shorter window, causing the checkpoint to broadcast earlier. This gives the next proposer more usable early-start time.

Overview
Small compromise to smoothen checkpoint construction, the last block should really be shorter. Palla's pr's with the multiplier also address this, however
I think that realistically we are only concerned with the last block being shorter.
