Code Review

This pull request upgrades the libtiff dependency from version 5 to 6 for apt-based installations of mrtrix3 from binaries. While this is necessary for newer operating systems like Ubuntu 22.04, it will break compatibility for users on older but still common systems like Ubuntu 20.04. My review includes a suggestion to add a comment to the code to document this important change in platform support.

[gemini-code-assist]

Upgrading to libtiff6 is necessary for newer Debian-based systems (e.g., Ubuntu 22.04), but it drops support for older LTS releases like Ubuntu 20.04 where only libtiff5 is available. This change in supported platforms is significant. To aid future maintenance, please add a comment clarifying the targeted distributions for this dependency.

-   libtiff6  # For Debian >= 11, Ubuntu >= 22.04. Older releases require libtiff5.
