YN-0146: nuke load exr with deep type autodetect

[ynbot]

Please describe the feature you have in mind and explain what the current shortcomings are?

Nuke can autodetect whether an EXR representation is typed as Deep image. This way we could avoid manual deep toggle in Loader options. And rather autoread it to deep reader. 

Client is suggesting deep exr type in discord link.

import OpenEXR

DEEP_EXR_TYPES = {OpenEXR.deepscanline, OpenEXR.deeptile}


def is_deep_exr(filename: str) -> bool:
    with OpenEXR.File(filename) as infile:
        header = infile.header()
        file_type = header.get("type")

        is_deep = file_type in DEEP_EXR_TYPES
        print(f"{is_deep=}")
        return is_deep

Questions to solve:

• If multilayer EXR with deep layer as one of many RGBA layers. Should user be able to manually override the deep detection?
• how to avoid OpenEXR dependency? https://discord.com/channels/517362899170230292/1433072461481775205/1433077840437448736
