unapplied_transfers

Represents a crosschain transfer that has been unapplied.

A cross-chain transfer that is past its deadline must be recalled or canceled. After doing so, unapply_transfer needs to be called on all chains where the transfer was applied before reverting it on the starting chain.

For example, if a chain going A -> B -> C -> D got cancelled or recalled on chain D, it must be unapplied on chain C, then on chain B, then reverted on chain A.
