Heatmap.js (using the leaflet plugin) uses its own canvas for rendering. if we allow leaflet-image to apply its usual logic behind canvas layers, the output is distorted. instead, i have it draw the heatmap's own exportable dataURL. I'm hoping that the way i wrote this is compatible with environments without heatmap.js.

As a side note, this is obviously not written in the best way possible, this was quick and goal-oriented code. I appreciate any suggestions for improvements. |

This allows users to export their map, in addition to their Heatmap.js data (using the leaflet-heatmap.js plugin) as a single image/canvas/whatever you want to call it.
I personally needed this and I was hoping I could find a solution but instead i wrote my own. (whoops)
