Refactor ISIS Diagnostics

[MohamedAlmaki]

This is preparation work for adding a new silicon analyzer in the indirect data reduction GUI. The goal is to refactor the ISIS Diagnostics tab to make it MVP-compatible and add unit tests.

Acceptance Criteria

• The Diagnostics tab is organised into a Model-View-Presenter pattern
• The View and presenter communicate using the Observer pattern (no qt connections)
• The Presenter and Model have automated tests

This issue has been automatically marked as stale because it has not had activity in 6 months. It will be closed in 7 days if no further activity occurs. Allowing issues to close as stale helps us filter out issues which can wait for future development time. All issues closed by stale bot act like normal issues; they can be searched for, commented on or reopened at any point. If you'd like a closed stale issue to be considered, feel free to either re-open the issue directly or contact a developer. To extend the lifetime of an issue please comment below, it helps us see that this is still affecting you and you want it fixed in the near-future. Extending the lifetime of an issue may cause the development team to prioritise it over other issues, which may be closed as stale instead.
