The current SudoswapProxy implementation cannot handle partial fills when an NFT is no longer available

[0xhiroshi]

The current SudoswapProxy's partial fill can only handle the case where the pool price moves out of the user's max cost. It will revert during safeTransferFrom if the NFT the user wants to purchase is no longer available.

Sudoswap will release a V2 router and it will be able to handle this scenario by checking that the token IDs are still in the pool before order execution, so we will wait until it goes live before integrating with Sudoswap again.
