[Feature] Support MPO files

[Piipperi]

I have searched the existing feature requests to make sure this is not a duplicate request.

The feature

I don't know if anything uses this format anymore, but the Nintendo 3DS-line appears to save 3D images in MPO format, and I have a couple of those in my iCloud Photos that fail to upload to Immich.

Unsure if this is viable to add as a supported file format, but posting this here as a request either way.

I have some of these in iCloud that were taken with a digital camera.
