* Convert BlockGHOSTDAGData from an interface to a public struct with getters * Move hashes.Less to externalapi so it can access the hashes directly without copying * Reduce calls to ghostdagstore.Get in blueWindow * Simplify the logic in RequiredDifficulty and reuse big.Int * Remove bigintpool as its no longer used * Use ChooseSelectedParent in RequiredDifficulty instead of looping over the parents * Remove comment
