Create function to calculate distance to nearest dam

[aweinert-MIT]

Create a python 3.x function to calculate the distance between a set of images and dams. The dam data can be download from the USACE National Inventory of Dams: https://nid.sec.usace.army.mil/ords/f?p=105:1::::::

• Inputs either a N X 1 imagery UUID or an image itself
• Calculate the distance, in units meters, between the latitude, longitude metadata of the image and all nearby dams
• Output a N X 4 column of UUID, image latitude, image longitude, distance to nearest dam, UUID of nearest dam

setup.sh will needed to be updated to download the dataset. A default data directory titled /data/USACE-NIB should be created to store the data.
