The transfer from the user into the router is supposed to happen in the router (we only support this in the executors for callback constrained protocols). This is necessary because of some security concerns that were found in the audit. This way we reduce the space of attack.
- Refactored TransferOptimization not to handle TransferTypes anymore but just return bools.
- Split get_transfer_type into get_transfers and get_in_between_transfer. Updates tests
- Updated the strategies to use this
- Updated function signatures to pass transfer_from and funds_receiver
- Updated SwapEncoders to handle this
- SplitSwapStrategy just assumes all tokens are sent to and from the router at all times
