New ASIF image format

Looks like Apple is introducing a new disk image format: https://eclecticlight.co/2025/06/12/macos-tahoe-brings-a-new-disk-image-format/

I'm curious what this means for Tart. If the files are sparse, that makes me think Tart might be able to ditch all the hole punching shenanigans when copying images to/from a registry, which would simplify the process a lot.

Yes, installing Tahoe in the next few weeks to play with it. The big question is if there are any downsides in I/O performance of the VM disk.
