More trip generators

Sports spaces look fine to me!

Railway stations

• The tooltip for name isn't working
• The .geojson file adds 1MB to the page load, bringing it from 3 to 4MB total. (Ctrl+Shift+I, Network tab in Firefox shows a useful running total). The pmtiles files are nice here, since they only load a few KB at a time. We don't need to switch formats here, but we do need to clean up the geojson file by only keeping properties we care about (name) and get this file to be smaller

Green spaces

I think we shouldn't add these in yet; they'll take more work to clean up and validate. First off, there are overlapping areas that wind up looking very weird:

We're picking up enormous conservation zones in the middle of the ocean:

We're missing valid green spaces like Blakeley Forest that even have footpaths through them. (See https://acteng.github.io/atip/more-trip-generators/browse.html#14.69/53.52992/-2.23673)

Based on Anna's (colleague at Turing) experiences trying to generate similar data from OSM and OS for another project, I think it'll take a while to refine this layer. In the meantime, the basemap already shows green space in a minimal way, so it's probably not too urgent.

Ah, the missing tooltips with railway stations are because the features don't have numeric IDs assigned in the geojson. Maplibre is frustratingly silent about this when they're missing :\
