- hardcoding some keccak256 that are otherwise computed at construction.
* hardcode keccak256 result
* Improve code readeability using try/catch
* Remove hardcoded hash
tests show that solc 0.8.0 does the optimization as expected
* Use try/catch to improve readability
* ERC165Checker: Do not revert when returndata is empty + new test
* Address PR comments

* using enum object to improve readability
* Fix unnamed return variable warning
