SSZ implementation for alloy primitives

[loocapro]

Motivation

I found my self needing to wrap alloy primitives types and implement SSZ on it. I thought it could be useful to have those trait implementations downstream.

Solution

Implementing SSZ as a conditional flag for alloy primitives.

Do you mind sharing more about your usecase? Are there other primitive types that would be useful with SSZ? We have so far restricted alloy to EL-layer tooling.

Hi @prestwich, we are running a custom reth implementation and we had to implement SSZ traits for alloy types.

So we thought that it might be useful to share our implementation and just consume it from alloy-primitives.

Other 2 types that we also implemented are U64 and U256 from reth::primitives which re-exports from ruint.

Cool, let me sync with the other maintainers and get back to this

Separately, I'd be in favor of a PR for SSZ support in the ruint support modules

Fine with me

Sure will also take care of it.
