Closes #1458

Goal

Create a standalone application. This application takes as input a scan (.nx file) and optionally an entry (aka data_path))

This standalone will display the widget.

src/tomer/app will contain the root script 'motion_correction.py' script of the application
src/tomwer/main.py should have add the command to the launcher (like for 'z-stitching')
tomwer.gui.reconstruction.nabu.motion_correction module should contain all the gui (widget...) at the exception of the orangecontrib main widget.
tomwer.task.reconstruction will contain the EwoksTask calling nabu-estimate-motion
@paleo gave us some test example: https://gitlab.esrf.fr/-/snippets/365
