New accordion icon

[vivdunstan]

Just added a new one, to use for my chromatic button accordion posts. This shows the correct accordion - my French chromatic button accordion made by Maugein. With the new to me non piano keyboard button grid on the treble side. I will keep using my other accordion icon (Paolo Soprani made red piano accordion, that I've had since 1981) for other accordion posts. I do like red!
