Fix AoG (#24)

* Update scales.md

* add all aesthetics

* Update AlgebraOfGraphicsExt.jl

* Add a legend elements definition, lifted from scatter

@@ -5,7 +5,7 @@ Beeswarm plots can be plotted in any combination of `xscale` and `yscale`.
 Specifically, beeswarm plots are correct in any [separable transform](https://geo.makie.org/stable/nonlinear_transforms/#Nonlinear-but-separable) - basically, any transform in which the x and y coordinates are independent of each other.  This excludes most geographic transformations, but includes any transformation you can make using `xscale` and `yscale` in a Makie `Axis`.
