Summary

sp1_primitives::Elf does not implement serde::Serialize / serde::Deserialize, while some related types (for example SP1VerifyingKey) already support serde.

Why this is useful

In my project, I need to persist an Elf object in a database.
Without serde support, I have to introduce a custom trait / custom serialization layer just for storing and loading this type.

If Elf implemented Serialize and Deserialize, it would be much easier to:

• store it in a database,
• cache it,
• pass it through application boundaries,
• reuse existing serde-compatible tooling.

My main use case is storing compiled ELF artifacts in a database and loading them back later without having to maintain a custom wrapper type.

Request

Would you be open to adding serde::{Serialize, Deserialize} for sp1_primitives::Elf?

If this change is welcome, I would be happy to work on a PR.
