stacks deep re-orgs are not handled properly #734
Description
Chainhooks v1 only handles re-orgs 6 blocks deep correctly. This is however a very old rule because Nakamoto re-orgs caused by Bitcoin may be hundreds of blocks deep, so when Chainhooks tries to resolve it we end up having an orphaned chain section that is never actually processed

This logic should be altered to deal with burnchain block count instead of Stacks block count
