miio issue
Hey there!
I've tried to update the plugin to latest version and it failed.

`EEXIST: file already exists, symlink '../lib/node_modules/homebridge-xiaomi-roborock-vacuum/miio/cli/index.js' -> '/usr/bin/miio'`

First package which I've installed with miio was homebridge-mi-air-purifier.
I can remove symlink etc., fix this install issue by myself, but it would be great for community if you would move your version of miio as separate repo (as before) - since original miio is not maintenaned anymore, I think community could work on that. I've got one update for miio too.
Think about that :-) Thanks for your hard work!
