GUI Rework

[keastrid]

A review and rework of the GUI on the Astronomy_ side of AIJ is needed, to optimize and get a better grasp on the threading issues experienced in the V5 update. This can occur during the headless/GUI split.

Goals

• Eliminate the threading issues
• Optimize the rendering
  • Don't redraw whole window for component update
  • Reduce needed draws
• Split the processing and GUI
  • Allows for headless operation
  • Improved scripting over macros
  • Automated tests via github actions/gradle
