Add start_height parameter to bitcoind_rpc::FilterIter::new #2126
Description
From evanlinjin's comment on bdk_wallet#368:
bitcoind_rpc::Emitter::new has a start_height parameter. This is used in the case the closest block that connects is below the start_height. So if the tip is reorged out, and we only have tip + genesis, we will start from start_height instead. To convey the wallet birthday with the checkpoint tip, while still taking into account reorgs, we can use tip_height - FINAL_DEPTH as the start_height parameter. FINAL_DEPTH can be as conservative as you want.
bitcoind_rpc::FilterIter::new does not have such a parameter. We can add it?
Then we provide docs as how to convey the wallet's birthday to the chain source using the checkpoint tip.

Hi @luisschwab, I started working on this issue and have opened PR #2205 implementing "start_height" support for "FilterIter".
Would appreciate any feedback/review. Thanks!

I don't think this should be part of the
bdk_chain 0.24release milestone since it's on it's own separate track. This change is not required forbdk_chain 0.24to function properly and it should not hold up the release.
