…d export regardless of error. Also various quality of life improvements

1. Made metadata processing more robust to deal with formatting errors / inconsistent writing the file in flickr.

2. Made the processing bar more useful with current filename shown

3. Added flag to block files from exporting if metadata or file processing fails. Previously it was blocking all the time. Now it doesn't block by default, and there's a flag if you want it to block export.

            Add this flag only if you want it block export if metadata or file processing fails. Leave it out and it will export the photo regardless of the failure.
            --export-block-if-failure

4. Added a flag for logging verbosity in the terminal while you are running the script.

            Add this flag to make the console output just show status bar while running and only show CRITICAL errors. If you don't include this flag it will show ERROR and CRITICAL.
            --quiet
