Logs and current optimization status

During optimizations (optimal control, calibration, model learning), a current best point is stored in the log folder to monitor progress. Called on a log file it will print a rich table of the current status. With the -w or -- watch options the table will keep updating.

c3/utils/log_reader.py -h

usage: log_reader.py [-h] [-w WATCH] log_file

positional arguments:
  log_file

optional arguments:
  -h, --help            show this help message and exit
  -w WATCH, --watch WATCH
                        Update the table every WATCH seconds.

Using the example log from the test folder:

c3/utils/log_reader.py test/sample_optim_log.c3log
