Distance to crop + crop coordinate should be saved to the database

[ivanzvonkov]

Context: The db_to_shapefile.ipynb notebook allows the user to query a set of street2sat object detection predictions and compute crop coordinates by estimating distance to crop and adding it to the photo coordinate (in the direction of the camera photo).

Issue: The computed coordinates are only saved to a shapefile which is not kept track of as part of the repository. Therefore distances have to be recomputed each time and comparison of different distance estimation methods is not straightforward.

Potential solution: On each crop coordinate computation the following values should be saved to the database:

• velocity vector
• distance estimation method
• distance estimated
• computed crop coordinate
