Use python package logging for adjustable debug/info output

[dkriegner]

We could use https://docs.python.org/3/library/logging.html to allow for an easily adjustable degree of logging output. The user could via a command line argument set the level of verbosity they expect in the output.

I am pretty sure this is a particularity of your command line. usually info output is not red. Warnings/errors might be red. In my command line actually no logging output is red. There are lots of things which can be configured via the "handler" of the logger

I do not like much the INFO:root: part. you can remove this as outlined for example here: https://stackoverflow.com/questions/8353594/can-python-log-output-without-inforoot

It can be also useful to output there some timestamp instead. This is usually more helpful than the default output.
