Add radial grids (#177)

Closes #172
Closes #178

Intended use is for a more interesting grid for use in asemic writing.

* [ ] (deferred to #6 and #179) Add `simplify` (and `densify`) tool
* [ ] (deferred to #180) Add generic `rhai` script to `transform` tool
* [x] Generate radial grid in x,y in `grid` tool
* [x] Make `--output-format=lines` output the rings as `POLYGON`s, so
that `smooth` smooths just them, and not the radial spokes.
  * [x] Maybe tunable enough that it should be its own `radial` tool?
