v0.1.3

• Windows: game folders with non-ASCII names. A copy of the game under, say,
  C:\Users\Jürgen\Games was never found: the program now uses UTF-8 file names (Windows 10
  1903 or later). CI builds the Windows version on every change and checks such a folder.
• Sound after a stall. When the sound device stopped asking for samples for a while (the
  system suspending it), the AdLib's writes could be lost and a note left sounding; they are
  all kept now.
