File rename?

[nvacsuf]

Try to figure out how to modify sliced file names before saving them.
image_slicer.slice(filename, 4, save=True)

Currently, this option it saves all of them in this format filename_01_01.jpg filename_01_02.jpg filename_02_01.jpg filename_02_02.jpg

Cannot find option to modify with the library.

I am looking to get this format. filename_1.jpg filename_2.jpg filename_3.jpg filename_4.jpg

Row and column number is included to enable tiles to be joined back together. Should be trivial to rename with a shell script. Pull requests to add this functionality to the library in a non-breaking way are welcome.
