Release v2.4.2.0 | GBG IDscan Documentation

Further improvements to the logic around how we find face landmarks for faces that are badly lit, occluded or have pronounced watermarks. Have also made some speed improvements when more complex algorithms need to be used for this process. Also fixed 2 bug in this area that would only have effected occluded faces.
Added enhanced logging of debug images. This is disabled by default for speed reasons.
This release requires AVX2 support.
