NAME:
    cbz-merger.sh Merges cbz files.

DESCRIPTION:
    This script does the following following for each .cbz file (configurable via --extension):
      1. Extract files to --temp-dir
      2. Rename files to cbz-filename_filename.
         F.ex. if there was a file 018.png inside Chapter1.cbz
         it would be renamed to Chapter1.cbz018.png
      3. Add renamed files to --output

    The renaming is done to keep ordering and not have duplicates inside the cbz file.
