I have been using loguru for a year now and I really like it. I think this could make the logging much easier for us.

There is the user aspect.
One could just do logger.add("alchemlyb.log") to save the log to a file.

Also one doesn't need to initialise a logger and the function name would just be printed to the start of the line.
For debugging purpose, the loguru would also print all the public variables to the log.
