feat PadLines: added "Mode" argument

Browse Source 
- Added "Mode" argument to the Pad Lines operation.
- Added "Fixed Count" mode. Mimics original behaviour, fixed number of characters added to the string.
- Added "Target Length" mode. Adds padding characters in order to reach a certain length.
- Modified Pad lines implementation to use join rather than slice for final result
