Pillow can raise ValueError("No data found for frame") on some MPOs when
seeking a later frame with missing/invalid data. This prevented LoadImage
from returning the successfully decoded primary image.

We wrap iteration of the frames and if first frame is ok(only for MPO format), we ignore other decoding errors.

Exception happens here: https://github.com/python-pillow/Pillow/blob/2ebb3e9964bcfb46e2b8dcaec1917caf67730a7d/src/PIL/MpoImagePlugin.py#L152-L155

Edited: Alternative PR was created with less changes and keeping the current logic.
