[bin] Fix all the scripts that had errors

- `meshroom_submit`: the submission to the render farm is now effective
(the script did not work at all).
- `meshroom_status`: the `--toNode` option did not work and caused errors.
- `meshroom_statistics`: some adjustments needed to be made for the script
to run with Python3 instead of Python2, an issue in the core/stats.py file
led the `statistics` file to never being read correctly, and the calls
to the Matplotlib API were outdated.
