Simple ASCII for progression of the process

[SuMinRo]

I am processing 1114 separate tiff files to a single stack. It's fine if it takes time, but it would be nice to see some kind of feedback that the process is still ongoing, rather than have halted for a mysterious reason.
I know it works for a small sample size of my files, but I cannot truly know it works in any capacity until it has managed to produce a desirable output, which might be a long time or never, depending on whether it works or not.

If it makes sense maybe add some ASCII messages like "400/1114", once it has reached that far.
