Return each Steam shortcut entry from shortcuts.vdf in hexadecimal, so each value can be individually parsed.

# shortcuts.vdf starts with different bytes than all other shortcuts, this magic basically translates to: '00shortcuts000030000002',
# where '0000' is spacing, '30' represents the shortcut index (1), '00' is more spacing, and '0002' is the start of the next column
