firmware 1.2

• pio_pkg_list.txt = dependency tree at time of release
• added audible usb plug/unplug notifications

• added “force click” setting — this replaces the old disable/enable click option in the settings menu, which toggled the same state as the host machine, with an independent override
• changed the initial click mode state to off
• changed the initial led indicator states to off
• fixed theoretical(?) race condition in buzzer management
• fixed errors in the README bindings table
