packPNG 2.0a — libpackPNG shared libs + in-memory API

packPNG 2.0a

LTS point release. Wire format unchanged — 2.0a decodes any 2.0x and vice-versa. This release is about the library (libpackPNG).

Motivated by an archiver-embedding request: a DLL with buffer functions (like packJPG's pjglib) and multithreading on by default.

What's new

• Shared libraries: libpackpng.so (Linux) and packpng.dll + import lib (libpackpng.dll.a) / packpng.def (Windows), alongside the static .a.
• In-memory API for archivers — buffer in → buffer out, no temp files needed at the call site:
  • packpng_compress_mem / packpng_decompress_mem / packpng_free
  • packpng_set_threads(n) (0 = auto)
• Multithreading ON by default in the library (auto = hardware threads).
• Verified byte-exact on Linux and Windows (file + memory API, static + DLL).

Assets
