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

When will this not be the router address that we use for approvals? It will always be the router address. address_for_approvals sounds to me very vague (which approvals?).
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
