Export the progress bar and reporting

The goal is to let users build their own tool if they want to, embedding autocannon.

How do you want the progress bar exported? I am thinking allowing the user to enter renderProgressBar: true in the options parameter will render the progress bar, as the bar itself is not an object which you can log, the output to console is managed internally in the progress bar.

To customise the rendering output of the bar, I would like to allow users to enter a progressBarDisplay: SOME_STRING in the options parameter, which would take a string in the format of the progress-bar module.

Does that sound okay for the progress bar?

Reporting: Do you just mean logging the run results in the table format?
