printer: rejigger how we use serde_derive

Browse Source 
The idea is that by bringing derives in via serde's optional feature, it
was inhibiting compilation speed[1]. We try to fix that by depending on
`serde_derive` as a distinct dependency.

It does seem to improve overall compilation time, but only by about 0.5
seconds. With that said, my machine has a lot of cores, so it's possible
this will help more on less powerful CPUs.
