`EspNowError` is not `Copy`

i dont see why this enum is not Copy. the internal Error variant is also not Copy, but its just u32s, so it could be.

Thanks! It guess it's just an oversight and actually not compliant with our developer guide ( https://github.com/esp-rs/esp-hal/blob/main/documentation/DEVELOPER-GUIDELINES.md#amendments-to-the-rust-api-guidelines ) - feel free to submit a PR

Otherwise we will eventually get to an overhaul of that module but it's currently not our focus

Yes it is

This was fixed in #4716
