Changes between 2.3 (released 2023-07-25) and 2.2 versions:

Add the Intersect class and the IntersectTool utility. The
methods are described in "Geodesic intersections",
https://arxiv.org/abs/2308.00495 (2023-08).
Add typedefs Geodesic::LineClass, GeodesicExact::LineClass,
Rhumb::LineClass, GeodesicLine::BaseClass,
GeodesicLineExact::BaseClass, RhumbLine::BaseClass.
Geodesic constructor accepts optional third argument exact, default
false. If true, then the calculations are delegated to
GeodesicExact. GeodSolve and Planimeter now use this simplified
interface.
PolygonAreaExact is deprecated; use PolygonArea instead.
Bug in Planimeter -Q (introduced in version 2.2) has been fixed.
TransverseMercator constructor accepts optional arguments exact
and extendp (default false for both). If exact = true, then the
calculations are delegated to TransverseMercatorExact.
TransverseMercatorProj now uses this simplified interface.
Minor fixes:
- Fix documentation bug for TransverseMercatorProj (incorrectly
  stated that -t for the extended domain was the default).
- Remove unnecessary friend declarations for Ellipsoid in
  AlbersEqualArea and TransverseMercator. (As of version 2.2,
  Ellipsoid uses the AuxLatitude class for this functionality.)
- Small change in EllipticFunction to speed up the default
  contructor.
- Remove workaround for boost 1.76 with enums (not needed for boost
  1.78).
- Remove unused header from NearestNeighbor.
