Create function to calculate distance to nearest port facility

[aweinert-MIT]

Create a python 3.x function to calculate the distance between a set of images and port facilities.

• 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 port facilities. The timestamp metadata will also need to be used when filtering landslides. Port facilities that opened after the image was taken should not be considered.
• Output a N X 4 column of UUID, image latitude, image longitude, distance to nearest port facilities, UUID of nearest port facilities

setup.sh will needed to be updated to download USDOT: Ports. A default data directory titled /data/USDOT-Ports should be created to store the data.
