v16.4.0

Feature

Added --cacheClear option for—you guessed it—clearing the cache 🫥.

This brings the suite of cache-related options to:

• --cache : Cache versions to the cache file.
• --cacheClear : Clear the default cache, or the cache file specified by --cacheFile.
• --cacheExpiration <min> : Cache expiration in minutes (default: 10).
• --cacheFile <path> : Filepath for the cache file (default: "~/.ncu-cache.json").

Thanks to @ly3xqhl8g9 whose code is gratefully more lucid than his username.
