Your Suggested Enhancement

Add support for reading presets directly from ZIP archives, and adding individual presets or directories from a ZIP to a preset playlist.

Playlists should support mixed sources, e.g. presers from the local file system and different ZIPs in the same playlist.

ZIP references can be stored or given on the command line (in --presetPath) such as zip://path/to/package.zip?/path/to/preset.milk.
