This is necessary when we run tycho-execution in an environment that already has a runtime.
Make sure that if no runtime exists, like in the testing scenario inside tycho-execution, we save the new runtime in an attribute of permit2. If we don't do this, then the runtime just dies and our handle points to nothing at all and all tests fail

- 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.
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)

The strategy works as follows:
- Manage approvals needed
- Compute min amount (if check amount is any):
- if slippage is defined, apply slippage on the expected amount and take the min value between that and the check amount
- if not, it's just the check amount
- Iterate through the swaps
- call the corresponding swap encoder to encode the swap
- add swap header (tokens indexes and split)
- ple encode the swaps
- Add extra inputs (amounts, token addresses, min amount, (un)wrap, number of tokens and receiver)
Misc:
- Move executor address and selector encoding inside the SwapEncoder
- Add default executor_selector to SwapEncoder
- Pass router address inside the SplitSwapStrategyEncoder
- Move Permit2 inside the SplitSwapStrategyEncoder. It is a responsibility and a specificity of the strategy to need permit2 approvals

This is a too early over generalisation. We need to encode the permit and the signature all together with the other method input variables. This way the return type will be specific to permit2 (instead Vec<u8>) anyway. For simplicity, decided to remove the generalisation and keep things simple

- Add data validations similar to the ones done in the Permit2 SDK
- Fix Domain main (!!!) It's Permit2 not Permit
- Return the whole function signature data (owner, permit_single, signature) encoded
test improvements:
- Don't compare the timestamps, this was making the test fail sometimes and pass other times
- Add a test to run on an anvil fork and actually call permit2 contract to double check the encoded data works
misc:
Rename get_allowance_data -> get_existing_allowance

- Retrieve allowance data from an RPC
- Encode approvals:
- Create PermitSingle (and PermitDetails)
- Use alloy eip712 to get signing hash on typed data
- Sign data
- Add chrono and alloy eip712 and signer-local to Cargo.toml

No more SingleSwapStrategyEncoder or SequentialStrategyEncoder
No more batch routing (so no need for batch permits as well). If multiple solutions are found, return multiple Transactions

ENG-4076 <#DTT#>
- 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
