sample exr to test file load time.

On my PC (i7 4770k) loading 4k EXR takes about 5 seconds, but Krita is ready for painting in about next 10 seconds.
I've compared it to PS and it loads EXR below 1 second and is ready immediately.
Hope it can be improved. Sample EXR attached.

I've checked larger file and 19k HDR takes here about 120 seconds to load. PS loads this file in about 8 seconds and seems not to be multithreaded here, takes about 15-16% of my CPU.
