To support converting structures like this into sfc_polygons ``` $`8cbe63562a54bff` lat lng 1 -37.82030 144.9833 2 -37.82019 144.9833 3 -37.82012 144.9832 4 -37.82016 144.9831 5 -37.82026 144.9831 6 -37.82033 144.9832...

Register C Callable

Inspired by [recent discussions and progress](https://github.com/paleolimbot/geoproj/issues/2) in other libraries, and by [`data.table`](https://github.com/Rdatatable/data.table/pull/4084) exposing their C functions, would you consider exposing the C functions from `geodist` so they can be called...

support Origin-Destination style data

actually - doing this in [`sfheders`](https://github.com/dcooley/sfheaders/issues/80)

```r geometries:::rcpp_rleid(1:20, 1:20) ```

hypertidy support

@mdsumner - I figured it would be good to sketch out designs / requirements for supporting scilicate / hypertidy structures and the like. I've started porting all the utility functions...

coordinates

General function to extract any dimensions, and any nesting of coordinates --- TODO v0.1 - [x] R-facing function - [x] return data.frame with column names - [ ] Vignette entry...

returning unique coordinates (and their indices).

A lot of the internal functions from `sfheaders`, like `get_sfc_coordinates()`, will have a lot of use. These need to be brought across and documented
