ImageData data assignment in Strict Mode

[eliorar]

img.data = imgData // this line is not working in strict mode (line 527 heatmap.js);
this.ctx.putImageData(img, x, y);
this._renderBoundaries = [1000, 1000, 0, 0];
the error is as follows:
TypeError: Cannot assign to read only property 'data' of #<ImageData>

Possible solution:
according to documentation:
https://developer.mozilla.org/en-US/docs/Web/API/ImageData
you should use only putImageData function, so removing img.data = imgData resolves the issue

fixed in Pull Request #315. img.data is being mutated by changes to imgData.
