Scripts: ota.py version 0.4 (#2020) 

* use basic sleep instead of busyloop
* print immediately when no sort option is specified, disable default hostname sort
* restructure
* update requirements.txt
* cli timeout arg, increase default timeout to ensure that all devices are found
* use black for formatting
* shorter ifs
