*	ui_remote: make event sending async	David Phillips	2021-03-13
\| \| \| \| \|	This makes the UI a bit snappier, as we no longer have to interrupt for each event, just on groups of them.

*	First cut of UI state machine	David Phillips	2021-03-13
	This patch adds a first skeleton/draft of the UI state machine, with the altimeter setting logic implemented at a basic level. It also adds a Python script which uses GDB/MI to simulate/inject UI events on a GDB remote (i.e. qemu-avr running the sim copy of the firmware).
