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

Changing C compression API for XUAST LDR: if unified quality level is not being used, and the lower level uastc_rdo_or_dct_quality parameter was set to 100, we would previously return an error. Now DCT is not enabled, as expected.

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.

Fixing a very rare 1-bit overflow in ETC1S SSE optimized colorspace error calculations (which are 32-bit vs. the plain C++ code's 64-bit). Ultimately the output would still be correct and transcodable, but this could cause a compressor assertion check to fail. Found during compressor fuzz testing.
