heatmap grid artifact on large data #34

Description

Hello,

Thank you so much for this amazing tool.
Have you encountered and possibly found a solution to the following drawing artifact on the heatmap canvas?

The dimensions of my data are (217, 516)

I researched this briefly, it seems like for the heatmap the only calls on canvas are fillRect and they don't draw strokes. However, with floating point widths and positions this is just an artifact of canvas rendering. I am using Firefox, but also confirmed this in Chrome. Rounding coordinates and width to integers removes the lines.
