Creation of NFT bundles

[antho1404]

A really interesting feature would be to have to possibility to create bundles of NFTs.

Currently, an order is created with one asset (erc20-721-1155) and can be filled with one other asset (erc20-721-1155).

Having many to many relationships could be interesting so we could still have the same behavior but expand it with

• Many assets for one asset (eg: a bundle of erc721 for a price in erc20)
• One asset for many assets (eg: a bid in erc20 to purchase many erc721)
• Many assets for many assets (eg: buy many erc721 in exchange for other erc721s "collection swap")

This could open many possibilities for applications built on top of the protocol, especially for marketing purposes, to sell collections of NFTs that can later be sold individually and open a whole new range of NFT trading.

For information, this is supported by 0x protocol and could be used as a reference.

@antho1404 that's a good idea and this can be easily done on the contract level
We should just implement new ITransferProxy and register it inside ExchangeV2

Much more is needed to be done on indexer/backend level

So, we have this feature in our sight
