feat: make error clonable
Overview
This makes candid::Error clonable, which makes it easier for downstream clients to also make their Error types cloneable.
I've made a related PR for agent-rs.
Considered Solutions
I can also work around by using Arc<T> in downstream clients.
Considerations
This shouldn't have any impact on security or performance. Anyone that was interacting directly with the Custom variant may have a breaking change since it is wrapped in an Arc<T> now.
I agree that making a major bump just for this feature is not worth the effort, so I'm fine with leaving this to sleep and in the meantime I will just to_string() downstream.
In addition to the previous discussion, in Rust the errors are not typically clonable. Closing it.
