Story: Modify accuracy metric to be based on DBSCAN output rather than pixels #5

Right now, Accuracy metric for the model is pixelwise; but with DBSCAN we can potentially cluster disjoint pionts and create a hull with them that encompasses a larger area than just pixels. This area can be compared with the area of truth data (verified shapefiles) to give out better accuracy metric.

[x] create clusters of positive pixels from predicted bitmap of image using DBSCAN.
[x] Create convex hulls for each cluster.
[x] Find IOU of resultant convex hulls and true bitmap
[x] Show the metric in output
