SettingsTester

A utility class for making test encodes. This can automatically parse strings like

--preset veryfast --crf [14/15/0.5] and will then run encodes with CRF 14, 14.5 and 15.

The same works with non stepping options like

--preset [fast,veryfast,slow,slower] or --sao [true,false] (can also use yes/no and y/n for these)

Keep in mind that this will create an encode for EVERY combination and not some order.

--preset [fast,veryfast,ultrafast] --crf [14/15/0.5] For example will end up with 9 encodes.
