StrategyCollectionOffer
This contract offers execution strategies for users to create maker bid offers for items in a collection. There are two available functions: 1. executeCollectionStrategyWithTakerAsk --> it applies to all itemIds in a collection 2. executeCollectionStrategyWithTakerAskWithProof --> it allows adding merkle proof criteria for tokenIds. 2. executeCollectionStrategyWithTakerAskWithAllowlist --> it allows adding merkle proof criteria for accounts.The bidder can only bid on 1 item id at a time. 1. If ERC721, the amount must be 1. 2. If ERC1155, the amount can be greater than 1.

Errors​
CollectionTypeInvalid​
error CollectionTypeInvalid()
It is returned is the collection type is not supported. For instance if the strategy is specific to hypercerts.
MerkleProofInvalid​
error MerkleProofInvalid()
It is returned if the merkle proof provided is invalid.
OrderInvalid​
error OrderInvalid()
It is returned if the order is permanently invalid. There may be an issue with the order formatting.
