Approach to updating my 700-series stick on Home Assistant OS

[kevin-david]

This is technically unsupported since in involves running a (temporary) additional container, but I figured someone else might find it useful.

I created a small container with all the necessary tools to flash an update and put it here: https://github.com/kevin-david/zwave-update-container

Combined with Portainer, this makes for a fairly straightforward update if you want to perform it without physically accessing the device, or moving it to another machine.

I also embedded the script suggested in #14 as well.

Feel free to make it more flexible or pull it into this project itself - will happily welcome any contributions.
