Added data extracts to avoid creating tasks with no features

[Sujanadh]

Issue:

• fix Creating task areas with no features should not be possible #37

Updates:

This PR now avoids creating tasks with no features in them when the AOI is splitted using the split_by_square algorithm.

• Data extracts are now passed to the logic in order to check if a task has any features in it or not. In case a task does not have osm features inside it , it won't be appended to the list of tasks generated by the algorithm.

The split by square tests are failing as I assume they need the data extract passed to them.

Once fixed, I will merge and create a new release, then update fmtm-splitter on hotosm/fmtm#1642 👍

Nice work by the way 😄

These pre-commit hooks aren't being installed on my system, failing every time.

No worries about the failing pre-commit tests here! They are failures linting the additional SQL files in the repo - I should set an exclusion 👍

To install the pre-commit hooks so they always run on the repo locally:

pip install pre-commit
pre-commit install

The hooks will run every time you try to commit and not allow you to commit if there are failures.
If you need to commit anyway despite errors, use the --no-verify flag:

git commit -m "fix: some fix" --no-verify
