Feature/updated sphinx payload keys (#5698)

* removed support for legacy packet types from NymCodec

I think nodes had plenty of time to upgrade given versioned variant was introduced in 2022

* temp: use local sphinx packet for development

* introduce new messages that use more efficient reply surbs encoding

* checks for incorrect encoding

* generate correct message depending on config value

* fixed current packet version

* made packet type selection configurable

* updated sphinx packet crate to the published version

* fixed wasm build

* fixes in outfox due to sphinx api changes

* additional tests

* clippy

* fixed log/tracing import
