`wire::Type` is only (publicly) used as the `CustomMessage` associated type in `CustomMessageReader`, where it has additional trait bounds on `Debug` and `Writeable`. The documentation for `Type` even mentions that you need to implement `Writeable` because this is the one place it is used. To make this more clear, we move the type bounds onto the trait itself and not on the associated type. This is also the only practical way to build C bindings for `Type` as we cannot have a concrete, single, `Type` struct in C which only optionally implements various subtraits, at least not without runtime checking of the type bounds.

wire::Typeis only (publicly) used as theCustomMessageassociated type in
CustomMessageReader, where it has additionaltrait bounds on
DebugandWriteable. The documentation forTypeeven mentions that you need to implementWriteablebecausethis is the one place it is used.
To make this more clear, we move the type bounds onto the trait
itself and not on the associated type.
This is also the only practical way to build C bindings for
Typeas we cannot have a concrete, single,
Typestruct in C which onlyoptionally implements various subtraits, at least not without
runtime checking of the type bounds.
Gonna need this for 0.0.101 bindings due to the above.
