StrategyHypercertCollectionOffer
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. The amount must be 1. 2. The units held at bid creation and ask execution time must be the same. 3. The units held by the item sold must be the same as the units held by the item bid.

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.
