Translate to projected crs

[Robinlovelace]

Currently the outputs are unprojected. You can set the centrepoint, e.g. as shown in the example:

zonebuilder-rust/examples/clockboard-example.rs

Line 9 in 34438a3

let cp = Point::new(-1.5, 53.8);

That creates a distorted zoning system in unhelpful units of decimal degrees, which looks decidedly egg-like, as illustrated in the reproducible example below:

setwd("~/github-orgs/zonebuilders/zonebuilder-rust/")
system("cargo run --example clockboard-example > zones_uk.geojson")
zones = sf::read_sf("zones_uk.geojson")
plot(zones)

^{Created on 2021-05-01 by the reprex package (v2.0.0)}

Here's the output with a base-map, even more egg-like.

library(tmap)
tmap_mode("view")
qtm(zones)
