EWM item: story 8567

This pull request introduces a new batch processing notebook for Bragg Edge fitting using the marimo framework.
The notebook guides the user through loading configurations, selecting folders for batch processing, verifying parameters, and running the batch processing.

Key changes include:

Introduction of the marimo framework:

• notebooks/batch_bragg_edge_fitting.py: Added import statements for marimo and initialized the marimo app.

Configuration loading and processing:

• notebooks/batch_bragg_edge_fitting.py: Implemented cells to load and display the base configuration from a JSON file, and process it into an IBeatlesUserConfig object.

Folder selection for batch processing:

• notebooks/batch_bragg_edge_fitting.py: Added cells to allow users to select multiple folders for batch processing and create a list of IBeatlesUserConfig objects for each sample.

Parameter verification:

• notebooks/batch_bragg_edge_fitting.py: Implemented cells to visualize the configuration parameters as tabs of accordions for user verification.

Batch processing execution:

• notebooks/batch_bragg_edge_fitting.py: Added cells to run the batch processing, display progress, and capture standard error output for each sample.

Testing instructions

• Install marimo with pip install marimo in the development environment
• Execute the notebook as notebook with marimo edit notebooks/batch_bragg_edge_fitting.py
• Change the default folder selection to a location on your system
• Follow the instructions
• After running through the notebook, close everything and try again in the app mode, i.e. marimo run notebooks/batch_bragg_edge_fitting.py
