Improve preprocess command logging

[TomyCesaille]

Problem

The poto logs are 'invisible' compared to the massive amount of Siril logs while it executes the ssf script.

Solution

Leverage https://github.com/sindresorhus/log-update (or https://github.com/sindresorhus/ora), eventually https://github.com/npkgz/cli-progress too, to display 1-10 lines of Siril logs maximum in the console in order to keep tracking Poto-Siril logs.

This is a good opportunity to persist Siril command outputs in files.
