[Miner] Microblock miner will occasionally produce a microblock stream fork #3620

Thanks to data reported by one of the Stacks blockchain miners, it has come to my attention that the Stacks microblock miner will occasionally produce microblock stream forks. Per SIP-005, this is a slashable offense. Other miners correctly produced PoisonMicroblock transactions in reaction to discovering the forked stream, but a correct miner should never be producing forked streams in the first place.

I can confirm that this is often the case on Stacks 2.1 testnet & is leading to many confusing situations during Zest Protocol demos. A fix has high priority for us 🙏
