 // SubPoolMarker ordered bitset responsible to sort transactions by sub-pools. Bits meaning:
 // 1. Minimum fee requirement. Set to 1 if feeCap of the transaction is no less than in-protocol parameter of minimal base fee. Set to 0 if feeCap is less than minimum base fee, which means this transaction will never be included into this particular chain.
 // 2. Absence of nonce gaps. Set to 1 for transactions whose nonce is N, state nonce for the sender is M, and there are transactions for all nonces between M and N from the same sender. Set to 0 is the transaction's nonce is divided from the state nonce by one or more nonce gaps.
