save() with modules where .connect() initializes device (such as RFID reader MFRC522)

I wish I had read these experiments before my own work on moving from console-connected to independent operation! Thank you for writing them up.

Because I am going to be controlling power to all connected devices, I assume that all connected devices may have been independently powered down, and so (and because of not liking to be reliant on save timing) I prefer to reconnect devices again via a deviceInit function in onInit which is also called in the start section of the main app.m
