dumpling 2.6.2

Changelog

• Fix bug where you couldn't dump online files for non-ascii usernames. They'll now be stored using alternative folder names.
• Decreased Dumpling's binary size by using libschrift instead of freetype2 for font rendering
• Optimized font rendering so that it's now 2x faster. This doesn't really improve dumping speed, although it might feel more responsive overall.

Thanks to @Maschell for telling me about libschrift!
