If compiled with --features=gifsicle, it will support lossy compression.

The C API doesn't require explicit decode thread setup any more.

• Fixed sorting of filenames, so image2.png is sorted before image10.png

It only took 6 months:

1. Buy a smart card.
2. Go through multi-step security theater based around e-mailing of easy-to-forge photos of documents that the recipient had no ability to verify anyway.
3. Install and configure weirdo bespoke software for the smart card. It opens an SSH-server-hanging popup asking for a PIN, so I can't have headless automatic builds.
4. Install certificates through Internet Explorer (the only browser supported by the security-minded Certificate Authority).
5. Copy & paste a bunch of obscure commands printing "Internal Error (0xF0AD)", documented for Windows Vista in form of Vogon poetry.

And now you have the gifski.exe with a digital signature! Obsolete SHA-1, no less! Thanks to this fantastic marvel of modern technology, instead of getting a scary window with "OMG every exe is a virus!" when running gifski.exe, now you get the fancy "OMG every exe is a virus! But from a Publisher" window.

Minor fix in the macOS and Windows versions

Fixed a crash on macOS and Linux.

Windows binary isn't up to date yet, and will crash from time to time, because building stuff on Windows is annoying. I'll sort it out later.

Note that animGIFs with transparency are limited to just 256 colors per frame. Opaque anims will look better.
