feat: add a util function to construct the create2 salt

[andreivladbrg]

Addresses #810

I decided to log the string salt to visually see what is being passed (also testing it, in case something is not working).

@smol-ninja, can you check, please, if I missed anything in the multi-chain script?

[smol-ninja]

LGTM! I haven't tested the scripts locally though.

Looks like the fork test fails are due to QuickNode?

[PaulRBerg]

I like this idea a lot - but we should absolutely test this new function in test/utils.

[andreivladbrg]

I don't think is related to QuickNode, since in periphery worked: sablier-labs/v2-periphery#280

[smol-ninja]

That looks like rate limiting imposed by Quicknode (2500 credits / sec).

[PaulRBerg]

Bummer. Let's try another provider - I will switch to ChainNodes.

Edit: done.

but we should absolutely test this new function in test/utils.

note: it would require to include --ffi flag in the test commands (locally) otherwise the tests would fail. e.g. forge test --no-match-test "testFork" --ffi

do you have any solution on how to fix this in the CI? how to include a flag in the command here:

do you have any solution on how to fix this in the CI?

Yes. We can add ffi = true in the Foundry config file.

This PR continues to be amazingly useful - @andreivladbrg you should tweet about it.
