no_std!!
this makes yaxpeax-arch no_std. generally nothing has changed w.r.t downstream crates, but a lot to do with colorization has been moved tweaked to make it no_std-friendly (specifically, allowing `termion` to be an optional dependency) this also makes address parsing optional, in the hopes that decode-only use cases don't need to involve as much machinery when building.
