Automatic logfile rotation seems to be missing

[mpvader]

Hi!

as dbus-shelly is now, I expect every user using it will run into trouble (full data partition, a really bad situation) at some point.

see see henne49/dbus-opendtu#173 for how I recommend to fix it.

Hey @Kotty666 , since you worked on this before, can I interest you in getting this fixed?

many people are copying this repo, and it is causing issue for us.

50Mb is also too much.

please make the code write to stdout instead of making its own log file - see above link.

@mpvader should be possible just done this few days ago at my dbus-growatt-shinex repository. But the interesting thing would be if @fabian-lauer had enough time to merge the request.
