Reading floppies and artifact floppies

[Umbire]

Per this set of lines, Geeks are (probably accidentally?) excluded from being able to properly "read" a pack of floppies: https://github.com/Soviet5lo/SlashTHEM/blob/d828e641d341175b5829bef070879bb163c7f636/src/apply.c#L3772-L3786

The Hacker's Master Boot Disk should also have its own messages when "read" this way.
