* Only compute finality_target's hash once
* Add missing documentation to Runtime APIs
* Add TODO about using `set_id` from `ScheduledChange` digest
* Make AncestryProof type more flexible
* Only import single finalized header instead of a chain
* Fix unchecked header import tests
* Add option for limiting ancestry proof size
* Update finality verifier Config in runtimes
* Update some documentation
* Fix Clippy warning
* Allow AncestryChecker to return proof size
Stops us from abusing the `Size` trait
* Remove Size impl for Vec<T>
* Remove size contraints for ancestry proofs
With different proof types its unclear how to "size" should be interpreted,
so we remove this requirement all together to avoid confusion.
