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.
