Description: Description\ In BitcoinProver.sol setMinConfirmations function set minConfirmations, but it doesnt check for max minConfirmations

1. Proof of Concept (PoC) File

   function setMinConfirmations(uint8 _newConfirmations) public onlyOwner {
       emit MinConfirmationsUpdate(_newConfirmations, minConfirmations);
       minConfirmations = _newConfirmations;
   }

   Recommendation

check _newConfirmations <= minConfirmations before set the new minConfirmations
