* 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>

With different proof types its unclear how to "size" should be interpreted,
so we remove this requirement all together to avoid confusion.

* Add some logging to the finality verifier pallet

* Add finality target to happy path log

* Add Finality Verifier pallet to runtimes

* Implement simple ancestry checker

* Use the new checker in runtimes

* Remove unused import warning

* Bump max allowed ancestry proof size

* Add a few optimization suggestions when verifying ancestry

* Use session length as upper bound for ancestry proof size

* Remove unused time units

* fixed call encoding in signature digets

* udpated test

* Add test for invalid set id.

* cargo fmt --all
