Add geometry to plant assets

[aislinnpearson]

Currently you can't add a geometry to a plant asset. Instead it defaults to the location geometry from the parent term.

However, the geometry for a plant asset often differs from the geometry of a field - especially at Harpenden where many of the fields have experiments in them, and the commercial asset is drilled around the experiments. This never used to be a problem as we didn't have GPS locations for the assets. Increasingly however, we will have geometry's for the actual plant assets which we will be able to estimate from the tractor location logs. It would also be useful to be able to add geometry to historic plant assets associated with experiments.

This would also impact:

This was partially resolved internally by Helen, who decided that plant assets split over two fields should incorporate two fields. The issue of having sub-sections of a field drilled with different crops wasn't address though, but is a very rare occurrence on our farms - hence why level 3 priority.
