Spherical point-in-polygon predicate (contains/within on Spherical())

[briochemc]

area has a Spherical() method, but the relation predicates (contains, within, …) are planar-only. A spherical winding-number point-in-polygon — correct across the antimeridian and at the poles — has no GO equivalent.

Could the predicates gain a Spherical() method? Note #416 (RelateNG DE-9IM engine) is planar (JTS/AdaptivePredicates in the plane), so it does not cover this. Context: an in-review GeoMakie PR (MakieOrg/GeoMakie.jl#381) carries a hand-rolled d3 polygonContains port to work around this — released GeoMakie does not have or need it. Related: #17, #333.

Yeah a successor to #416 will cover that, mainly waiting for Claude mythos to come back up though

Will it, though? 😁 More seriously, Opus not good enough for this you think?

[asinghvi17]

Yeah, I tried with opus and it was substantially worse for this (mainly because there is a good amount of overcomplication which Mythos/Fable are able to avoid)
