Fixed issue #394 - missing _mm256_storeu2_m128i macro

Please look at the issue #394 for exact error while installing Kvazaar.
I tried installing it on Ubuntu 20.04 (2 different machines). I only tried this version Kvazaar v2.3.0-24-ga909ddd2 2024-02-02
Apparently, the macro _mm256_storeu2_m128i definition was missing from Intel Intrinsic header, so I added it directly in kvazaar > src > strategies > avx2 > quant-avx2.c.
After that I was able to successfully install and run kvazaar to encode an mp4 video to hevc format.

Thanks, however please instead add the definition for the macro to this file https://github.com/ultravideo/kvazaar/blob/master/src/strategies/missing-intel-intrinsics.h#L22 inside the #if COMPILE_INTEL_AVX2 block and add check if the definition already exists, and include the header in the quant-avx2.c file
