Logging functionallity

[kstppd]

So this does loguru as a dep to analysator but makes it so that the verbosity can be controlled by an env flag/

This now uses logging.

• export ANALYSATOR_LOG_LEVEL=INFO will print what used to be printed
• export ANALYSATOR_LOG_LEVEL=WARN will silence any prints
• The default behavior remains unchanged.

print outs now look like so:

INFO:Using matplotlib version 3.7.3
INFO:Note: Unable to switch to TkAgg backend
INFO:Found population proton
INFO:Found population proton

#248 - use built-in logger instead?

#248 - use built-in logger instead?

This now uses logging and the log level can be set by setting ANALYSATOR_LOG_LEVEL.

This is good. Noting here the logging functions and levels:
https://docs.python.org/3/library/logging.html#logging-levels

So these logging message levels are named, and can be then adjusted to be used. A bit of overlap now with warnings, but those IMO have still their place (since those outputs are non-repeating), not quite sure about these ones.

logging.debug('A DEBUG message')
logging.info('An INFO message')
logging.warning('A WARNING message')
logging.error('An ERROR message')
logging.critical('A CRITICAL message')
