split360Images with dualfisheye mode always outputs black images.

[pmolodo]

Hi - I've been trying to use aliceVision_utils_split360Images.exe (in the Meshroom-2021.1.0 release) to split some dualfisheye images I have, but no matter what format or options I use, the resulting output images are always black.

For inputs, I've tried 8-bit jpgs, 16bit pngs, and 32bit float exrs. For outputs, I've tried all 3 presets (center, top, bottom).

I'm attaching a sample jpg:

...and here's a link to a zip with one of each format (the exr and png are both too large to upload to github):

I should also note that the original source is a .dng, but my camera (Insta360 One X2) spits them out in vertical mode, so I fed them through darktable to apply a rotation to get into horizontal. (Support for dual fisheye images in vertical orientation would also be nice!)
