Add command line input argument to set log file

[IshaanDesai]

By default the Micro Manager parses the log output to the terminal (sys.stdout). To parse the output to a file, the user has to manually pipe it, by doing something like micro-manager-precice &> micro-manager.log. This is inconvenient and error-prone. This PR adds a command line argument to the Micro Manager executable which accepts a log file name. It works in the following way

micro-manager-precice micro-manager-config.json micro-manager.log

The log will be parsed to the file micro-manager.log. Passing a log file is optional.
