Backup and restore as extra exec (not within shallow_flash), fixes #17.
Shot at #5 and #14 – needs confirmation.
Added readme to script folder to clarify their origin, closes #10.
Make device attribute mandatory and strict argument parsing to prevent accidents.
Shallow vs deep flash including ASCII art, fixes #12
Better ASCII art. Version bump
Moved from spawn to exec as shallow_flash's getopt acted up between different nix derivates. Added more logging to warn users about the time spend without log written to the stdout
