Currently the compositor reads cryptomatte meta-data from the render result. When loading a multilayer open exr file the meta-data was ignored. This patch will also load the cryptomatte meta-data from multilayer open exr files. This enabled workflows where the rendering and compositing are done in separate scenes or for future changes where the cryptomatte node will use the meta-data for name matching and color picking.
