Improve terminal printout

[misi9170]

This small PR fixes some bad formatting in the printout provided by Hercules. It also removes the line stating the speed-up of Hercules relative to real time, as this probably isn't super relevant for most users and can be easily calculated from what is still printed to screen. However, this second change can be easily reverted if we still want the speed up information.

Example printout prior to the change:

I'm not totally sure what the read in verbose flag = False is meant to be used for, so perhaps that could also be addressed in this PR?

Pull request overview

This PR improves Hercules’ terminal/log output by cleaning up the end-of-run timing summary, making it more readable and removing the “x real time” line that was previously printed as a tuple.

Changes:

• Replace tuple-based logging of “Total simulated time” with a single formatted string.
• Format wall time with units and fixed precision, and remove the “Rate of simulation … x real time” log line.

@genevievestarke @paulf81 tagging you in case you have any other suggestions for cleaning up the screen printout while I'm at it (and perhaps weigh in on the read in verbose flag bit)

I changed it so that it only prints out if verbose = True. I also got rid of an old AMR wind file I found floating around in the examples. This seemed like a good PR to put that in, too!
