now you can do stuff like:
```
gherkin_bump_layout("g20") {
upside_down() key();
};
```
and it'll work! you still have to specify the profile in the layout itself because row and column are not special variables... hm
rediscovered my old keysets file, adapted the functionality to make a flexible base layout tool.
also tweaked double sculpting to generically sculpt to both hands. it works, but it still needs more refinement, and the best layouts are going to be hand-generated anyways
