Don't make selector() a member of the StrategyEncoder trait. It is needed only for certain strategies. The strategy should manage it itself.

ENG-4081 Took 17 minutes
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

- 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
