feat: add dependencies to MultiBindingsInner

[Autoparallel]

Motivation

This seeks to close #2599 and should link to Foundry PR #5836. The intent is to be able to allow for serde::{Deserialize, Serialize} to be derived on contract bindings either via module or crate.

PR here has the intent of providing support for an additional dependency in the Cargo.toml generated when bindings are output as a crate.

Solution

This solution here seems a bit simplistic and forcefully assumes the end user will want a specific version of serde as an included dependency. It could be good, instead, to:

• Allow for dependencies to be chosen if there are extra derives added to the crate.
• Also forcefully add the serde derives to the contract bindings at this level.
• Check for most recent serde version or the version used within ethers-rs directly.

Let me know if we wish to make any of the above changes or otherwise!

PR Checklist

• Added Tests
• Added Documentation
• Breaking changes

hmm I don't think we serde by default here

what we need is a setter function just like MultiBindings::format

ethers-rs/ethers-contract/ethers-contract-abigen/src/multi.rs

Lines 395 to 402 in a65abb5

	/// Specify whether to format the code or not. True by default.
	///
	/// This will use [`prettyplease`], so the resulting formatted code **will not** be affected by
	/// the local `rustfmt` version or config.
	pub fn format(mut self, format: bool) -> Self {
	self.format = format;
	self
	}

so that this can be set manually:

MultiBindings::dependencies(impl IntoIter<impl Into<String>) -> Self

@mattsse you think this is good a enough approach?

I'll fix linter issues. Any tests or anything you need me to add here? Doesn't seem breaking!

[mattsse]

just want this addressed, then this is good to merge

#2606 (comment)

[Autoparallel]

Ah okay I will get to it. My jet lagged brain missed your comment! 😅

[Autoparallel]

Alright, I think that does it. I appreciate the help and I see how that externalizes it now and it seems to be working with a slight change in Foundry now too.

[Autoparallel]

@mattsse just checking in on this, I just ran the formatter and hoping this passes now.
