bigcurve: Adaptive Densification of Lines for Map Projections

Densify lines adaptively, as required by the curvature a map projection imposes on them. Edges are read as great circle arcs, and vertices are inserted along them only where the projected curve deviates from a straight chord by more than a tolerance measured on the map, following the adaptive resampling method of the 'd3-geo' 'JavaScript' library described in Bostock (2016) <https://github.com/d3/d3-geo>. Projections are computed with the 'PROJ' coordinate transformation library (<https://proj.org/>), so any coordinate reference system it supports can be a target. Inputs can be coordinate matrices, segment meshes or vertex pool topology from 'wkpool', and edges shared by neighbouring polygons receive identical new vertices.
