Users who run CLI EXOTIC (via terminal) may require an x/y coordinate solution in lieu of the Colab Bokeh solution

When running the terminal version of EXOTIC users are prompted to enter the x/y coordinates of the target star and the comp stars, but the terminal version does not currently have a solution for this. Users need to either use the Google Colab approach which loads one of the user's image files (stretched) or some other tool (e.g., ASTAP, etc.).
