We only support cyclical trades when the repeated token is the first and the last token in the swap. We don't support cycles in between

Also:
- Remove amount_out_min. Our reasoning is that we perform high-level final amount checks anyway (and expect users to do the same). Lower-level USV4 min amount checks are redundant.
- 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)

This is unnecessary since we already have the executor address loaded at build time

This way we don't have issues with paths and trying to read files that are at other locations after compile time

- 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.
- Tried not to leave a single public function undocumented, though did not double-document public function with obvious names
- Remove all mentions of the strategy selector in favour of the strategy registry (to avoid confusion)
Interface changes:
- Rename StrategySelector to StrategyEncoderRegistry
- Implement clone for SwapEncoder
The StrategyEncoderRegistry needs to be initialised at the highest level and the passed to the TychoEncoder.
The TychoEncoder doesn't hold the chain nor the signer_pk as attributes anymore
The StrategyEncoderRegistry does:
- Initialises the SwapEncoderRegistry
- Initialises all the strategies and saves them in a HashMap
- Later, the TychoEncoder only reads from this hashmap
The StrategyEncoder now each holds a SwapEncoderRegistry as an attribute and they use this to get the correct SwapEncoder instead of reading from the global SWAP_ENCODER_REGISTRY
Simplified the SwapEncoderRegistry to not need a Config (everything is done inside itself)
All SwapEncoders implement clone

Because of the renaming, git couldn't identify the new files and handle the conflicts gracefully.
Copied implementation for ExecutorStrategyEncoder from main
Rollbacked on decision to encode the executor address and selector inside the SwapEncoders. This is only necessary for certain strategies. So it should be done at the strategy level

This was confusing me when I had all of them open at the same time. Better to be extra explicit

Pass the signer's private key as a string around and only create a PrivateKeySigner inside Permit2 (where it's needed)
Use tycho-core Chain instead of Alloy ChainID. Create a temp method to convert between them
Create a EVMSwapEncoder that implements the executor_selector (that is evm specific)
