Add helper to filter pending transactions

[mattsse]

Describe the feature

similar to:

reth/crates/transaction-pool/src/traits.rs

Lines 355 to 359 in ff9a42a

	/// Returns all pending transactions sent by a given user
	fn get_pending_transactions_by_sender(
	&self,
	sender: Address,
	) -> Vec<Arc<ValidPoolTransaction<Self::Transaction>>>;

but should accept a predicate FnMut(&ValidPoolTransaction<Self::Transaction>>>) -> bool

can I take this?

[lakshya-sky]

@mattsse what would be the use case for this proposed function. does it make sense to add similar function to TxPool so that get_pending_transactions_by_sender can use the newly added function?

[mattsse]

not quite, lookup by sender is faster,

what this new function should do instead is essentially a iter().filter().collect()

[gakonst]

Is there a next step which integrates these with the PayloadBuilder trait, so that one can build customized payload builder strategies from the txpool?
