LibLayaX 1.0.15: models in one .tar file, weight codecs, and the GPU support under Wine

What's new

A model in one .tar file. laya_create now takes the path of an uncompressed .tar
file where it takes a model folder, and reads every file of the model from it. Nothing is
unpacked to disk, and loading takes the same time and memory as from a folder.

Codecs for the weights. A new function, laya_set_codec, lets a program decode the
stored bytes of model.safetensors with a function of its own while a model loads. It works
the same for a model folder and for a .tar file.

A fourth Windows x64 package, vulkan-compat-sse42. CPU and GPU backends on the SSE4.2
baseline, for x64 programs under an emulator that offers no AVX, such as Wine on an Apple
Silicon Mac.

Fixes

• GPU under Wine 10.20 and later. The first question on the GPU stopped the program with
  Assertion failed: !status && "vkQueueSubmit". Wine returned no queue for the way the
  engine asked for it; the queue is now fetched in a way Wine accepts.
• Apple GPUs from Windows and Linux builds. Large full-precision passes are now split for
  an Apple GPU in every build, as the macOS build already did.

Compatibility

The API version is still 1. The ten existing functions are unchanged and laya_set_codec is
the eleventh, so programs and bindings written for 1.0.14 work with these libraries as they
are. On the CPU, 1.0.15 gives the same answers as 1.0.14.

A program that must also run with older libraries can look laya_set_codec up at run time;
see Model files.

Packages

System	Package
Windows x64	avx2, compat-sse42, vulkan, vulkan-compat-sse42
Windows ARM64	arm64
Linux	x86_64 (folders avx2, compat-sse42, vulkan), arm64
macOS	arm64, arm64-vulkan, x86_64-avx2, x86_64-compat-sse42

The vulkan packages run on the CPU or the GPU; the others run on the CPU.

Tested

• Windows x64 and Linux x86-64, on the CPU with a test model: the library's test suite passes
  (54 checks) with all seven libraries, and the answers match 1.0.14.
• .tar models and codecs: 23 cases (three tar formats, long names, variant folders, stored
  weights with and without a codec, damaged archives), all as expected on Linux and on
  Windows under Wine.
• GPU from a Windows x64 program under Wine on an Apple M3 Ultra: answers match the CPU, in
  full and half precision, confirmed with a diagnostic build of this version.
