Integration with leafmap

[soxofaan]

https://leafmap.org/:

Leafmap is a Python package for interactive mapping and geospatial analysis with minimal coding in a Jupyter environment.

It would be great if we somehow can streamline using leafmap based visualization of openeo (batch job) data. Adding it as a base dependency is probably to heavy, but having it as a optional dependency should be doable

Additional use case: selecting input bbox, like what's now done in this eo_utils helper script.
