Drop jsonargparse for our ConfigParser

We have our own configuration parser tool ConfigParser and we should use it instead of jsonargparse.

Split the run function in two:

• Move this block to a new extract(*args) function
• Move this block to a new split(*args) function

We will need two commands:

• atr-data-generator extract that calls extract with the needed arguments
• atr-data-generator split that calls split with the needed arguments

You can keep ImageArgs and drop

• FilterArgs
• SplitArgs
• SelectArgs
