Removes an imported Asset Collection.
Un-importing an Asset Collection will not remove the collection from
the Solana blockchain. However, it will remove the collection from GameShift.
As a result, the collection will no longer appear in any queries, and neither
will any assets belonging to the collection. Furthermore, it will prevent
you from being able to use GameShift to initiate asset transfers, marketplace
interactions, and other asset actions for any assets that belong to the
collection.
