Support .tar.gz maps and map-system toggle

Add Apache Commons Compress dependency and relocate its packages for shading. Introduce a config guard (map-system.enabled) in SpeedHG.onWorldInit and DataPackManager.install to skip internal map handling when an external map system is enabled. Add untar() to WorldManager using TarArchiveInputStream + GzipCompressorInputStream and update extraction logic to handle .zip and .gz (.tar.gz) archives, extracting to the world parent folder as needed.
