EXR: multi-threaded exr image loading

Browse Source 
EXR files internally are split into independent "parts", which can
be decoded separately. Tinyexr already supports that via
TINYEXR_USE_THREAD.

Time taken to load 4K video resolution EXR files, on Ryzen 5950X/VS2022:
- FP16 file (27MB): 536ms -> 77ms
- FP32 file (69MB): 793ms -> 118ms
