✨ New features and enhancements:

• Stub server: Added missing methods to DataLabStubServer to support new DataLab features

  • Added remove_object() method (removes an object from DataLab)
  • Added call_method() method (simulates calling a method on DataLab's main interface or panels)

• Test infrastructure: Refactored visualization code in test suite for better maintainability

  • Centralized PlotPy visualization utilities in sigima.viz module
  • Added standardized helper functions: create_curve(), create_image(), create_circle(), create_segment(), create_cursor(), create_marker(), and create_contour_shapes()
  • Updated all interactive test functions to use the new unified API instead of direct PlotPy builder calls
  • Improved code consistency across signal and image test modules

• Visualization backend flexibility: Added support for Matplotlib as an alternative to PlotPy for test visualizations

  • New configuration option viz_backend to select visualization library ("auto", "plotpy", or "matplotlib")
  • Environment variable SIGIMA_VIZ_BACKEND can override configuration
  • Automatic fallback from PlotPy to Matplotlib when PlotPy is not available

• Jupyter notebook HTML representation: Added rich HTML display for Sigima objects in Jupyter notebooks

  • SignalObj displays shape, dtype, X/Y ranges, axis labels, and title in a formatted table
  • ImageObj displays shape, dtype, value range, origin, pixel spacing, extent, axis labels, and title
  • ROI objects (BaseSingleROI, BaseROI) display their geometric properties
  • BaseCoordinates and derived classes display point coordinates
  • TableResult and GeometryResult display result data with source object information
  • Centralized CSS styling in HTML_TABLE_CSS constant for consistent appearance
