bitcoind_rpc!: bring back CheckPoints to Emitter

Browse Source 
* `bdk_chain` dependency is added. In the future, we will introduce a
  separate `bdk_core` crate to contain shared types.
* replace `Emitter::new` with `from_height` and `from_checkpoint`
  * `from_height` emits from the given start height
  * `from_checkpoint` uses the provided cp to find agreement point
* introduce logic that ensures emitted blocks can connect with
  receiver's `LocalChain`
* in our rpc example, we can now `expect()` chain updates to always
  since we are using checkpoints and receiving blocks in order
