v must be [0,1] converts to nearest ISE index with proper precise rounding

Selector "val" ranges from 0-3 and is a direct index into g_etc1_inten_tables.

* ZSTD_decodeSequence(): * @p longOffsets : tells the decoder to reload more bit while decoding large offsets * only used in 32-bit

! ZSTD_getDictID_fromDDict() : * Provides the dictID of the dictionary loaded into `ddict`. * If @return == 0, the dictionary is not conformant to

ZSTD_getFrameHeader_advanced() : * decode Frame Header, or require larger `srcSize`. * note : only works for formats ZSTD_f_zstd1 and ZSTD_f_zstd1

Encoder library initialization (just call once at startup)

Results scaled by # block texels (block-SSE in weight space)

~2x faster than decode_block(), but XUASTC LDR only. pUpsampled_weights_to_use must be at block res, [0,64], single plane blocks ONLY

High-level convenience decode. Opens the KTX2 file bytes for you.

decoded in ASTC order, not linear order return false if the ISE endpoint quantization leads to non-valid endpoints being decoded
