codj v0.2.2

DJ mode waveforms stay readable on loud tracks:

• the beat grid shows through the bars, and the loop turns its bars green
• hot cues in the waveforms are their letters in their pad colours
• the overview dims the part already played, so you see where you are in the track at a glance
• the bottom key strip no longer cuts an item in half on narrow screens
