Dev 2.4.0

[AtoraSuunva]

• Removed furry.booru.org since they have CloudFlare browser verification enabled.
  • As far as I know, there's no (intended) way to bypass this if you're not a browser.
  • Added CloudFlare-specific error message if this happens in the future
• Add fix for Paheal changing their API response format
• Make example.js only specify the "cat" default tag if you don't specify a site
• Change from tsc -> typescript for package.json scripts, since tsc is deprecated.
• Update dependencies
