Switch Heatmaps to be for each side respectively

The analysis and storage now contain two different heatmaps for the CT and T sides respectively.

However on the frontend I currently just have them all listed out with the side as a prefix, which is
not very useful and we should more change the data structure to essentially send the two heatmaps for
a player as a single data structure and then in the view display them side by side. However I am not
100% how to best achieve this
