SimdYuv420pSaveAsJpegToMemory #226

I'm very impressed by SimdYuv420pSaveAsJpegToMemorybut there is a problem with the colour space conversion. If I go from YUV420P to JPEG and back, the images look washed. Is there a colour space mismatch or is this caused by JPEG compression?

Also please note when choosing SimdPixelFormatNoneI get BGR, not YUV420P.

JPEG is image format with loss (except quality =100) so it can cause wash. As to color space see documetaion of function SimdYuv420pSaveAsJpegToMemory: http://ermig1979.github.io/Simd/help/group__image__io.html#gac0ee5c58a3d4de7540d52e7356d2dbab
