0.2.1

Changed

• Raised the minimum dependency versions to SwiftSoup 2.13.7,
  swift-argument-parser 1.8.2, and swift-docc-plugin 1.5.0.
• The package now declares Swift language mode 5 alongside mode 6, so a package
  that has not moved to mode 6 can still depend on SwiftACD. The required Swift
  tools version is unchanged at 6.3.

Fixed

• Documentation: the Domain Enums topic no longer links to WingPosition,
  EnginePosition, TailConfiguration, or LandingGearConfiguration, which
  the library does not define — Recognition exposes those fields as String?.
  Parser.init(directory:) links to Downloader.downloadAll(errorCallback:)
  with its argument label, so the symbol resolves.
