multi-channel exr reader and cryptomatte masks extractor

Half of my environment  textures are rendered in 3d package.    Shape splatter  never gives you same  pixel-to-pixel  quality .   Always  aliased  alpha.  Never true nice AO ,  Never  true physics aware small things non-intersecting each other.    You instantly see it's fake unless it's something  only quite sparsely scattered.

And what amazes me more is that  some modern GPU renders  actually  works faster than shape spatters stack togeter with all their UV channel to color data extract nodes   giving you an illusion of proceduralism  while  being unresponsive as hell  and rather  hang your substance.  

So I would really love  cryptomatte masks extracting node and milti layered  exr importer.
