[REQ] Add miniumum OS version to DMG formats.

[IronCraftMan]

Is your feature request related to a problem? Please describe

When compressing to DMG, I'd like to be able to quickly see which version of macOS supports each compression type.

Describe the solution you'd like

It would be nice if, after each format name, it lists the minimum supported version, such as "ULFO (LZFSE, 10.11+)"

Describe alternatives you've considered

I can check the man page for hdiutil, but it'd be better if I could just quickly see it within Keka.

Additional context

They're listed in man hdiutil, under the "convert" verb.
