GEOSNearestPoints method's arguments/return 'string' types need to be 'number'

GEOSNearestPoints method's argument/return string types need to be number from geos CAPI definition (https://github.com/libgeos/geos/blob/3.12.0/capi/geos_c.h.in#L3226-L3239).

Great find! It looks like you fixed it already, would you be willing to create a PR?

[sanak]

Oh, yes. I ran git stash locally, so I will create PR with #24 side.
