Describe this PR

• We should be able to collect new polygon and linestring geoms with this update.
• By default all new projects are type 'polygon' / 'geoshape'.
• The type of geometry to draw needs to be configured at project creation.
• Setting the new_geom_type param will also modify the XLSForm as needed to the correct geometry type.

Future todo:

• Add field / selection to project creation workflow in frontend.
• Work out why the polygon drawing is a bit flaky:
  • They seem to complete on the third vertice being drawn.
  • It's possible to draw more by holding the click, dragging the map slightly, then releasing the click.
  • Probably some conflict with the default MapLibre click handler?
• Note that I didn't add any extra toolbar buttons to the map. It's not possible to edit verticies, as this is probably done on a phone and that would be too fiddly. The user will just have to create a new geom if they make a mistake.

I tested this locally using odk collect in mobile phone.
It works exactly as expected for new polygons. I didn't see any way to create new linestrings yet.
Approving for polygons only.
