Getting tokens of an 1155 contract

Both onchain and premint (gaslessly created) tokens of a Zora 1155 contract can be retrieved using the the Collector Client function getTokensOfContract() and passing a token contract address. The function returns a tokens array with an item for each token of the contract. Each item in tokens contains information the token in the token object, and has a function prepareMint. The prepareMint function takes a quantity to mint and returns the transaction parameters to mint the token, costs to mint the token, and any necessary erc20 approvals that must be executed before minting the token.
