interpolateTransform* can't interpolate rotation from 0 to 360 deg

[iseeyou911]

Hello
interpolateTransform* interpolate rotation with shortest path. So, looks like it's imposible to make interpolation from 0 to 360 deg. I think this is an issue.

d3-interpolate/src/transform/index.js

Line 21 in 255231b

if (a - b > 180) b += 360; else if (b - a > 180) a += 360; // shortest path

@iseeyou911 this behavior matches the CSS spec
