Share geometry across devices and apps => QR code containing geometry as GeoJSON
See #3373 for more details

@andreia-ferreira as per the new reqs discussed on Friday this will likely have a dependency on google/ground-platform#2485 now.

New requirements we discussed:

• No need for now to have interoperability with the receiving app WeMo (being developed by EFI - European Forestry Institution) , as the app is not live yet. A direct integration could be a future follow up if they are not able to consume the geojson directly
• Making the location available in geosjon format is useful for EUDR, where geojson format is required
• Agreed to provide both formats:

1. A QR code which provides the geojson of the polygon, in text format as the raw geojson, and including the geoid.
2. A link URL to the geoid of the polygon, which can be shared through a share button (example link) (at a minimum a copy action to easily copy and paste it into any app like WhatsApp)
   Both options require the device using Ground to have online connectivity (to synch with the server and generate the GeoID - requires implementation of [Asset registry] Connect to new apis for saving LOIs and obtaining geoids ground-platform#2485 )
   The person receiving the share could be offline (but for option 2 they will need to go online to open the URL).
   @andreia-ferreira shout if I missed anything. @jo-spek FYI

From Gino: dangerous to assume we will always have online connectivity to complete the submission - currently Ground is built around the assumption you don't on the submission screen (you do for example after the synch status screen)
Next steps:

• WHIMO app team need to specify what format and app intent they are expecting:
• geojson, any specific structure?
• universal mime type? Or specific app deeplink?
• can they just build a QR scanner to their app to read it?
• @jo-spek to set up a call with WHIMO app team to discuss the details
