Unused imports traits

[mcr]

I don't quite understand how this is building/passing-CI.
Without this change, I get the following with rustc 1.92. I got this with previous versions of rustc.
(rustc 1.94-nightly also shows this problem, as did 1.93-nightly and 1.90)
[noting that: "feature[stmt_expr_attributes]" in src/lib.rs is not allowed without -nightly]

Hrmm I will need to investigate what the problem could be because I have never seen this before and never had this problem.

For the CreateCommandOutputHandler the only thing that needs to be removed is ffi_data_handler.ffi_creation_ticket_ptr = null_mut();. I am not super happy about that class even though I am the one who created it. I think I was a little bit to zealous. It would be better if it could zeroize the pointer values on drop. Not sure if that is something that is possible.

For pub(crate) use impl_mu_aliases; just remove everything that has to do with that. Not sure why I added it.
