Improve precompile times

[SimonDanisch]

While AoG is just a relatively small wrapper around Makie, it introduces signficant compile times. One big reason for this seems to be the heavy use of NamedTuples, which introduces compiles times for the same plot, when one just changes one keyword. The first step should be, to try to move to Dict as early in the pipeline as possible and then look from there what else can be improved.

Any news?

The SpecApi is a big step towards AoG with almost no compile times, once we use it more internally!
