v0.10 - Collection-based orders

Adds Collection-based orders to NFT Swap SDK. (Also can be used as 'floor-based' orders).

🔥 Under 105k gas 🔥

These orders can be filled using any NFT from a particular collection.

The SDK provides a simple API:

// Maker creates an order for any NFT from a collection (you can think of it as a 'bid')
// Specifically in this example, the maker will sell 1000 USDC for any NFT in the collection specified
const v4Erc721Order = nftSwap.buildCollectionBasedOrder(
  // Selling ERC20
  {
    type: "ERC20",
    tokenAddress: USDC_TOKEN_ADDRESS,
    amount: "100000000000000", // 1000 USDC
  },
  // Bidding on any NFT in the collection
  {
    tokenAddress: NFT_CONTRACT_ADDDRESS,
    type: "ERC721", // "ERC721" | "ERC1155"
  },
  makerWalletAddress // Maker wallet address
)

const signedOrder = await nftSwap.signOrder(v4Erc721Order)

// Later, taker can sell an NFT from the specified collection, filling the bid.
const fillTx = await nftSwap.fillSignedCollectionOrder(
  signedOrder,
  "11045" // Token ID from the collection to fill order with
)
