/**
* Loads and displays DICOM Microscopy Bulk Simple Annotations.
*
* This utility function:
* 1. Retrieves series metadata from a DICOMweb server using study and series instance UIDs
* 2. Converts metadata into MicroscopyBulkSimpleAnnotations objects
* 3. Adds annotations to the viewer in groups (identified by AnnotationGroupUID)
* 4. Applies a consistent yellow color ([255, 234, 0]) to all annotation groups
* 5. Makes the annotation groups visible in the viewer
*
* @param {Object} params - The parameters object
* @param {Object} params.microscopyService - Service for handling microscopy operations
* @param {Object} params.displaySet - The display set containing metadata
* @param {Object} params.extensionManager - Manager for extensions
* @param {Object} params.servicesManager - Manager for services
* @returns {Promise} A promise that resolves with the loaded display set
