HAOS should be installable from a USB drive

With the rapid development of HA, things seem to break often enough that I need to rebuild my software system or revert to an earlier version to keep running several times a year. I don’t know how many more times I can remove the SSD from my NUC with its fragile connectors to image HAOS directly to it from another computer via a USB to SATA cable. Ubuntu and Windows can be installed from an external drive so it would seem that HAOS could be, too. In fact, it is on the Nabu Casa Blue and Amber boxes so why not on standard x86 machines.
