Tatum fork of awesome OpenZeppelin contracts library

Tatum made some small changes to ERC-20, ERC-721 and ERC-1155 contracts and modified by their needs.

• ERC-721 deployed by Tatum is one of the following:
  • Tatum721General.sol - Ownable OpenSea compatible NFT standard with batch mint functionalities
  • Tatum721Cashback.sol - fixed price royalty cashback forced by blockchain - OpenSea not compatible
  • Tatum721Provenance - percentage based royalties forced by blockchain - OpenSea not compatible
