[Feature] Slope Layer Variants / Slope Ramps

[V0pT]

I've noticed a few things when using slopes/slope layers that I think could possibly use improvement. An issue I've found with the current slope layer, for example, is that you cannot start raising the bottom half of a slope until the top half is already at max height, which makes creating long ramps out of slope layers impossible. This is a tad frustrating for an infrastructure nerd like me, who likes to build disability ramps everywhere.

An alternate/additional thing that would be amazing is to have vertical and stacked slope layers, like the new half-layers in 2.2 (amazing update by the way, you guys cooked HARD).
