- For protocols like Balancer and Curve, which expect funds to be in the router at the time of swap, we must support also transferring funds from the user into the router. Doing this in the router would mean we are dealing with transfers in two different places: in the router main methods and in the executors. To avoid this, we are now performing transfers just in the executors, and two transfer types have been added to support transfers into the router.
TODO:
- Add this for Balancer and Curve (only added for USV4 atm).
- TODO consider renaming TRANSFER_FROM and TRANSFER_PERMIT2 to include "pool" in the name
- Also do some renamings and comment improvements:
transfer method -> type
- Remove integration tests since we no longer support direct calls to USV3 executor, even for testing.
- The tycho router address default is set at the EncoderBuilder level (not inside the strategies)
- Rename TychoCoreChain to TychoCommonChain
- Only take TychoCommonChain as an argument at the outermost level: EncoderBuilder. Everywhere else we use the execution Chain right away

We have a trait TychoEncoder and then two implementations: TychoRouterEncoder and TychoExecutorEncoder.
This way we go a level above with the decision if it is a direct execution or if it should use the tycho router.
- Created two builders: one for each tycho encoder
- Delete ExecutorStrategyEncoder and move code straight into the TychoExecutorEncoder
- Add validate_solution to trait TychoEncoder
- Move group_swaps.rs a level up
- Update tests and usage cases
Doing this we get rid of all that weird stuff we were doing before
