Logger: Add progress bar

When we reverse the offsets, we might need to wait a long time. Therefore a progress bar is a nice feature to provide.

This implements #738 (closed) and is dependent on !1265 (merged).

@pdraper Can you take a quick look at the function: tools_print_progress_bar (especially the part where I am getting the terminal size) and tell me if you see some function calls that we should avoid please? Thanks!
