Issue: #335

Hola chic@s

I fixed the issue #335
I have copied the interfaces IERC721Enumerable and IERC721Metadata to /contracts/interfaces to avoid path error with last openzepplin-contracts version.

In IERC721Enumerable and IERC721Metadata:

• Change import path from './IERC721.sol' to '@openzeppelin/contracts/token/ERC721/IERC721.sol'
• Change compiler version from 'pragma solidity >=0.6.2 <0.8.0' to 'pragma solidity >=0.7.5' to match v3-periphery compiler and allows project that implement last version of openzeppelin-contract to compile

For the compiler version I understand it can be an issue but since I changed it only on interfacex, I guess it is safe.

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
