The `rpc_requests` macro requires the `tracing` library to be installed

[matheus23]

Trying to use irpc::rpc_requests on a struct in a crate without the tracing macro will make it fail.

I think it should be possible to have tracing as a dependency in irpc-derive and then the macro should work? (Ideally we also use some macro hygene like using ::tracing, etc.)

I don't think adding deps to irpc-derive will help. This will just make the macro depend on tracing, not the crate that uses the macro. It's the same with serde, btw. Not sure if there is something you can do about this other than document it.
