Watch Pro Tools Solo Mode (AFL + Latch) on the Studio B Mac Studio

A LaunchAgent helper on that Mac (Accessibility) reads Options > Solo Mode
every second into a status file and ticks AFL/Latch on request. APPS
alarms PT SOLO NOT AFL (hold fixes it; in the Sunday auto-fix list) and
PT SOLO CHECK OFF when the helper is not running or not allowed.
