Compile photo source data

[mmannion]

Notes from Teams chat:

• Craig gave us a tour of some photos in Aquarius and described how they are stored
  • Most Locations don't have photos
  • Locations that do have photos may have a bunch
  • Not all will be relevant for Survey123
  • There is not reliable metadata we can use to automatically determine which should be attached to a Location and which should be attached to a MeasuringPoint in our model
• [ ] TO DO: We need to develop an approach, ideally automated but possibly manual, for compiling the photos we want to view in Survey123 and tagging them so that we can load them to the right place
