BRC721._checkOnERC721Received(address,address,uint256,bytes) (contracts/bsc-nft-factory/contracts/BRC721.sol#367-386) ignores return value by IERC721Receiver(to).onERC721Received(_msgSender(),from,tokenId,_data) (contracts/bsc-nft-factory/contracts/BRC721.sol#371-382)
Ensure that all the return values of the function calls are used.

BRC721.constructor(address,string,string).admin_ (contracts/bsc-nft-factory/contracts/BRC721.sol#49) lacks a zero-check on :
- _admin = admin_ (contracts/bsc-nft-factory/contracts/BRC721.sol#50)
Check that the address is not zero.
