Santiago Palladino c46f0353d1 Update ERC721 to latest 1.11.0 from OpenZeppelin-solidity (#11)
* Update ERC721 to latest 1.11.0 from OpenZeppelin-solidity

* Hardcode supported interfaces instead of using lookup table. This avoids shifting storage when extending supports interface.

* Update build artifacts

* Fix linter errors
