This way the user is responsible for encoding the Tycho Router method inputs that are used as guardrails in execution.
Interface changes:
- Create EncodedSolution
- StrategyEncoder
- don't need to know have permit2 or token_in_already_in_router as attributes anymore
- encode_strategy returns EncodedSolution now (no method encoding done here now)
- TychoEncoder
- add encode_solution() method. This is the recommended method for users
- needs to have permit2, token_in_already_in_router and router_address as attributes
- permit creation is made in the router now
Also:
- create encoding_utils.rs
- update all tests

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

- It has two three methods to be created:
- new: where the user can pass any custom StrategyEncoder
- tycho_router: where the default SplitSwapStrategyEncoder with Tycho Router will be used
- direct_execution: where the user can encode only the execution data and integrate this into their workflow.
- This replaces StrategyEncoderRegistry
- EVMTychoEncoder holds directly the StrategyEncoder and not the registry (per one init of the EVMTychoEncoder there is only one possible StrategyEncoder)
- Update quickstart
- Update bin (add subcommands to bin to create a different instance of EVMEncoderBuilder)

Return selector in the StrategyEncoder. This is needed for the ExecutorStrategyEncoder

- This way this chain object contains everything we need, we don't need to worry about doing any transformation or calling any supplementary functions inside any of the encoders
- Needed to move our new Chain object to a higher level since this is used in the higher-level encoder traits. This required some weird default values in the constants in order to avoid using alloy's hex literal. I could have instead opted to make Bytes parse a string I think, though this would mean possibly returning an error at the constants level, which is not nice either.
Question:
- Do we want the user to be in charge of passing the native and wrapped token every single time? This may be a bit annoying for the user. For now, I have defaulted to those in constants.rs, this would take 5 mins to remove though if you don't like it, and it would get rid of this complicated bytes initialization.
Validates:
- Proper sequence of input, output, and first/last swap tokens for wrap/unwrap cases
- All solutions contain at least one swap
- Only exact in solutions are inputted (since we don't yet support exact out)
- Move all evm code inside evm directory
- StrategyEncoder:
- Kept StrategyEncoder trait but created a new one: EVMStrategyEncoder to implement encode_protocol_header (that is evm specific).
- All StrategyEncoders implement both traits now
- Renamed DefaultStrategySelector -> EVMStrategySelector
- RouterEncoder:
- Created a RouterEncoder trait and a EVMRouterEncoder that implements it
- Moved utils inside evm directory as well
- Renamed config.json -> executor_addresses.json and moved it to a higher config directory
- Make alloy optional and dependent on the evm feature gate
