Modular BECMonitor and ConfigDialog

Main Features:

BECMonitor

• Standalone widget (bec_widgets/widgets/monitor.py) which can be used for visualisation of live data acquisition based on the config dict very similar to the one used in the bec_widgets/examples/extreme.py
• Inherits from pg.GraphicsLayoutWidget
• To use it in the application you can promote in QtDesigner defining the class and header (see example in attached screenshot)
• example of use as a three separate widgets can be found in examples/modular_app/modular_app.py where one has to just connect ConfigDialog to the correct BECMonitor
• Close #15

ConfigDialog

• Property editor for BECMonitor where one can setup what devices should be plotted and Crete different configurations for different incoming scans
• Configurations can be imported/exported to .yaml files for later use.

Minor Features:

Mostly utility function in bec_widgets/qt_utis

• yaml_dialog.py → simple function which opens QFileDialog for saving/loading .yaml and convert from/it dict → close #25
• BECTable → inherited QTableWidget just with function to delete rows with Backspace/Delete
• widget_hierarchy.py → debugging tool to print out the hierarchy of the widget and pick up the values from certain widgets

Future plans

BECMonitor

• on_scan_segment can be refactored into separate class with multiple method for more modular validation of the incoming data from the redis → created #27 (closed)
• custom right click context menu #30 (closed)

ConfigDialog

• Validation tool for importing/exporting .yaml, probably based on pydantic and json schema.
• Autocompletion for line edits → user will be only able to add devices which are loaded in the current bec instance. #23 (closed)
• Option to not pass entries, just names on devices and rely on ._hints. #28 (closed)
• Colorbutton in signals table to set colors of rendered curves. #29 (closed)
• Color palette comboBox with color scheme preview. #20 (closed)
