- .basis transcoder class now validates the basis_slice_desc structs to ensure the original (unpadded) dimensions are valid, not too large (beyond 16K on either dimension), and are in sync with the slice's block dimensions. All methods that parse the slice desc structs now validate the contents first.
...
- basisu_lowlevel_etc1s_transcoder::transcode_slice(): Added PVRTC temp buf malloc buffer size sanity checking
Thanks to Canxuepiao Jian for the report.

expanding this table by 1 entry to 256 entries total to silence static analysis - in reality, the access can mathematically never go beyond the original size 255 array, but it's best to be safe

Add missing #include <exception> for std::terminate
...
container_abort() calls std::terminate() but the file does not include <exception>. This compiles on most toolchains today because other headers transitively pull it in, but fails on Android NDK r28 (Clang 19) with C++23 where the transitive include no longer happens.
Same class of issue as #395 (missing <ctype.h> in this file).

Fixing 2 issues found via artificial encoder fuzzing, impacting the ASTC HDR 6x6/UASTC HDR 6x6i codec:

minor fix to assert range check in bc6hf so basist::MAX_HALF_FLOAT is encodable (this can't happen in our normal ASTC HDR path, as values this large can't normally be encoded)

v2.1 update for KTX-Software and Khronos file format KTX2 compatibility.
...
This update impacts the UASTC HDR 4x4, UASTC HDR 6x6i, and XUASTC LDR formats. New KTX2 files in these specific formats using v2.1 can't be loaded using v2.0, however we've kept backwards compatibility with all of our previously written KTX2 files. (v2.1 can transcode all previously written files.)
This is part of our effort to be compatible with Khronos's specification.
bc6hf encoder's smooth block path updated to handle inputs with texels close to MAX_HALF_FLOAT.
Adding command line options to basisu tool so it can write either v2.0 or v1.6 compatible UASTC HDR 6x6i files. The default is v1.6.
Updating WebGL KTX2 testbed so on ASTC devices it automatically switches between sRGB or linear internal formats for the created texture.

Fix CMake Unity builds
...
transcoder/basisu_astc_helpers.h has a pragma once, but it is also an
implementation header (when ASTC_HELPERS_IMPLEMENTATION is defined).
pragma once is not necessary here as the header has a separate ifdef
guard, and it blocks attempts to compile Basis as a CMake Unity build
(CMAKE_UNITY_BUILD=ON) or as a single-translation unit non-CMake build
if the helpers header has been included earlier in the TU, as the second
inclusion with implementation defined doesn't actually include the
header.

Adding KTX2 transcoding/encoding/decompression to PNG/KTX1 support to the transcoder, encoder, JavaScript wrappers. This is also adding Zstandard to the repo, which is optional. Set BASISD_SUPPORT_KTX2_ZSTD=0 when compiling the encoder/transcoder to disable it, or from cmake set KTX2_ZSTANDARD=FALSE.
