Issue DM-1551: Prototype HTM-based spatial binning to visualize large number of catalog sources
Currently we are using a generic 2-d binning algorithm, that is finding minimum and maximum values of the two columns to be visualized and bins the values into 2-d grid with the specified number of grid cells. This algorithm distorts data in the pole regions and whenever data are on both sides of ra=0. More smart binning based on a spatial index is necessary when reducing the number of (ra,dec) entries intended for visualization.
