Update measurements side panel in OHIF to display both instance and series annotations, group by type

Part of #81 (closed). Update the side panel so that it is possible to display series annotations by their type with series and instance annotations appearing in a collapsible accordion (aggregated across the entire study).

Requirements:

• Load data from the measurements service (#86 (closed))
• Display instance measurements (angles, points, regions of interest) and series annotations
  • When clicked the viewer should jump to the series/measurement (current module behavior, though it needs to be refined)
  • Measurements and annotations should be split by group/type.
  • Measurements
  • Annotations (series level annotations)
  • Pending (refer below for more detail)
• When new measurements are added to a series (either annotations or from OHIF tools), they should be added to a new section called "Pendng."
  • When there are unsaved measurements a "Save Measurements" button should be visible.
  • When clicked, the button should prompt the user for a description for the report.
  • The module should then create a DICOM-SR document and upload it to the PACS server. This option should only be available if the user has upload permissions to the server.
