Create a prompt window to allow users to choose between running a new analysis or recalculating already analyzed images

Users of our image analysis software have requested the ability to choose between running a new analysis or recalculating already analyzed images. This feature will give users greater flexibility and control over their analysis workflows.

Requirements:

• [x] Create a new window that is displayed when the user opens the software.
• [x] The window should display two options: "Run New Analysis" and "Recalculate Analyzed Images".
• [x] When the user selects "Run New Analysis," the software should perform a new analysis on the chosen images using default or user-specified settings.
• [x] When the user selects "Recalculate Analyzed Images," the software should allow the user to choose which images to recalculate using default or user-specified settings.
• [x] The window should also include a "Cancel" button allowing the user to exit the window without selecting.

The idea for the future: We can add minimalistic instructions on the screen or include more information in the user manual.
