Title: remove file suffix if there is only one file output

In most situations, we only need the `full` image, currently, even if given the option `-F -o filename`, I still get `filename-full.png`, which is really inconvenient.

This PR remove the `-full, -thumb, -clipped` file suffix if there is only one file generated.
