[ui] Add display for ROMA matcher

[servantftransperfect]

This pull request extends the application's support for the RomaReducer node, ensuring it is recognized as a provider of features and matches folders in both the backend and the UI. The changes update relevant logic to include RomaReducer alongside existing node types, improving consistency and functionality when handling feature and match data.

Backend and UI support for RomaReducer:

• Added RomaReducer to the featureProvider and matchProvider node type lists, so it is now treated as a valid source of features and matches folders in the reconstruction pipeline (meshroom/ui/reconstruction.py).

UI logic for features folders:

• Updated the logic in Viewer2D.qml to recognize RomaReducer as a node type that provides a features folder, ensuring its output is included in the results shown in the UI (meshroom/ui/qml/Viewer/Viewer2D.qml).
