feat: new format for shuttle_index

1. Bump "version" to 3
2. Rename "shuttle" to "name"
2. Rename "mux" to "projects", and turn it from a dict into a list
3. Project entries: add "address" (which was previously the key of the "mux" dict), remove "features" and add optional "analog_pins" with a list of analog pin assignment.
