Modify change area notebook to use util functions

[hannah-rae]

Modifying the change area estimation notebook to use the same(ish) util functions created for the (single year) area estimation notebook

This requires the following steps:

• [ ] Adapt existing notebook to use util functions
• [ ] Add code for computing area estimates from confusion matrix (was not in notebook previously)
• [ ] Test by comparing change area estimates for Tigray computed using this notebook and prior analysis (outside repo)
• [ ] Test by computing change area estimates for new ROI (e.g., Bure or Jimma)

Is this ready for review @hannah-rae? First time I see these draft PRs 🤔

[ivanzvonkov]

@hannah-rae should this be closed or on the path to merging? FYI on colab pip install shapely==1.8.5 is required to avoid an cartopy import error

@adebowaledaniel Could you clarify what's happened here?

1. Hannah opened a PR to use some of the new util functions
2. You updated some of the util functions Is this correct?

[adebowaledaniel]

Yes, @ivanzvonkov, It updated the following:

• the load_ne function to dissolve regions/states (Admin level 1) geometries into one,
• m^2 to Ha conversion,
• and the unittest for area_util.

Some tasks still need to be completed for this PR; I plan to review them in the coming week.

• [ ] Add code for computing area estimates from confusion matrix (was not in notebook previously)
• [ ] Test by comparing change area estimates for Tigray computed using this notebook and prior analysis (outside repo)
• [ ] Test by computing change area estimates for new ROI (e.g., Bure or Jimma)

Since the recent changes are needed, especially for single-year area estimation, I will implement them in #212 and merge them.

Close w/ merge of #314
