- Also added integration test to test the optimizations, where we can see the in and out transfers being optimized if we enable verbose foundry testing
- Fixed typo in swap encoder builder initialization
- Needed to add ekubo and uniswap v4 to callback-limited protocols.
- I had to bump the fork block in all of our integration tests: The way it was before meant that certain integration tests were using certain executor addresses, and others were using different ones, because of the redeployment. This was a pain to account for on the rust side. Instead, all tests now use an Ekubo-compatible fork block. Values needed to be updated because of price changes between blocks.
This way we can define protocol and chain specific addresses in this file and use them in the Encoders

We don't know the pool tokens in the ProtocolComponent, so we can't infer the indexes correctly. Added a call to the MetaRegistry curve contract to get the correct token indexes. To do this, I had to move the get_client to utils. We could actually refactor the transaction logic into its' own struct and use it here and in the approval logic
It was assumed that all the pools will have a "factory" static attribute, even if empty

- Created methods to deploy the router and the executors. Whenever we use rollFork we need to redeploy everything! Notice that the addresses will be different then!
- Created a test_executor_addresses.json to be used in the encoding tests, this way the calldata for the integration tests is already correct and we don't need to do any manual replacing (this was annoying). The addresses in this file match with the addresses used in the solidity tests

- The router address can be set when creating the SplitSwapStrategy, which now takes an Option<Bytes> as input during initialization (another breaking interface change)
- This change allows us to change our router address in the future with minimal effect on the users. Users should only pass the router address in the split swap initialization if they intend to use their own router for execution.
- This change also means that the router address does not need to be passed with the solution, even when using the executor strategy (which was pointless).
- I thought of having a router_address() method to set this in the encoder builder - but it seemed too messy, since we don't need the router address for execution for example. We would then potentially unnecessarily load and set the default router address when not needed. It is also not even used at the highest level EVMTychoEncoder, so it makes more sense for it to be directly associated with the swap strategy instead.
- Users will now not be able to encode for different routers without re-initializing the strategy. We assumed this use case to be very rare and not worth supporting.
- add integration test
- cannot directly call _handleCallback from the locked method of the tycho router because of bytes memory to bytes callback conversion
- Rename to EkuboPoolKey because of conflict with USV4 pool key
- Bonus: fix bug where input token to swap method must be ERC20 (we should also support ETH)
- Add deployed executor address to json
- Build proper encoder for pancake v3
- Increase gas limit when setting executors (costs more since we set one more)
- Fix json filename in scripts/README.md
