Add Filter Option Flag or Preferences for Cloning Remote Repository

[enricocap]

Currently, SourceGit provides an "extra parameters" space where users can type various options when cloning a remote repository. It would be beneficial to have a dedicated flag for the filter option, making it more user-friendly and accessible. Alternatively, adding a preferences option for cloning repositories could provide a more flexible and customizable experience.

• Introduce a new flag for the filter option in the cloning process.
• Alternatively, add a preferences option where users can set their preferred cloning options, including the filter option.
