GEOSwift Versions Save

• #259 Expose GeometryConvertible.makeValid(method:).
• Fix warnings when building tests with Xcode 14.3.

• #250 Add GeometryConvertible.snap(to:).
• #255 Add GeometryConvertible.hausdorffDistance(to:) and GeometryConvertible.hausdorffDistance(to:densifyFraction:).
• #256 Add GeometryConvertible.concaveHull(withRatio:allowHoles:).
• #247 Add Sendable conformances and more Hashable conformances.
• Update to GEOSwift/geos 8.1.0 (geos 3.11.2)

• #224 GeometryConvertible.buffer(by:) can now be used with negative widths.
• #232 Dependency and tooling support updates:
  • Updates to GEOSwift/geos 7.0.0 (libgeos/geos 3.10.1)
  • Increases swift-tools-version to 5.3 (corresponds to Xcode 12)
  • Drops support for Carthage
  • Reorganizes sources to match Swift Package Manager conventions
• #235 Added GeometryConvertible.symmetricDifference(with:)
• #236 Updated LineStringConvertible methods to use implementations from geos:
  • normalizedDistanceFromStart(toProjectionOf:): The geos implementation returns 0 for 0-length lines, whereas the old GEOSwift implementation threw GEOSwiftError.lengthIsZero, which has now been removed.
  • interpolatedPoint(withFraction:)

Added GeometryConvertible.simplify(withTolerance:)

Adds isValid, isValidReason, and isValidDetail
