Add stub methods/functions, add basic build and start of the CBF chain source as well as basic struct containing the fields which undoubtedtly are needed.
Previously tests assumed that the chain source of the lightning node and is node which mines. This is not the case with CBF chain source which needs to wait until after mining a new block a new tips propagates to it. `wait_for_block` is made to return a new height and a new function `wait_for_node_tip` is added which waits until the given height is processed (returned via `status.best_block` ) on a given node.
Ask wallet for revealed spks, register them. Implement `Listen` trait ans add register_script method as well as implementation of registered scripts/outputs.
When `process_kyoto_events` processes events it decides whether we need to take any action (e.g. apply block). These actions are sent to a new abstraction — `BlockApplicator` which holds `ChainListener` (which in turn has wallets and can apply blocks / filtered blocks). This `BlockApplicator` has to have a receiver of a channel (and `process_kyoto_events` has to have a sender to this channel. Thus we cannot create them in `new`, because we would own them at `CbfChainSource`, so they are created in `start`. Also this commit ran `cargo fmt --all` which was missed previously.
