Drop vertices from a geometry while keeping its shape.

Drop vertices from a geometry while keeping its shape. Use it to cut a boundary down before a call whose cost is vertex-driven -- POST /v1/pip caps on points times polygon vertices, and POST /v1/geometry/buffer and the overlay ops cap at 2000 positions -- and to shrink what you store or draw. The response reports outputVertices next to inputVertices, so the saving is measurable before you spend again. The algorithm is Douglas-Peucker. Send toleranceMeters for a ground tolerance applied isotropically: both axes are scaled to metres at the input's centre latitude first, so at 70 deg N the simplification is not three times as aggressive east-west as north-south, which a raw degree tolerance makes it. Send tolerance instead for the raw degree tolerance if you want turf's behaviour unchanged. Retained vertices come back exactly as sent rather than round-tripped through the scaling. Not topology-preserving: adjacent polygons simplified separately can gap or overlap along a shared edge. Input is EPSG:4326 only. Limits: 100000 positions across the whole document, 1 MiB request body.
