Disable pin hovering effect

[m1l73r]

Hello!
Thank you for making this library, I'm really happy with it so far!

I have an issue though with the pins, since i cant seem to find a way to disable the pin animation when hovering.
I have made my own pin, but even with that i cant find a way to disable the animation.

Is there a way to disable the pin hovering effect?

Best regards
Johan

I've implemented simple size increase for pins, but no customization for it.
If your use-case requires customizing it - I'd gladly review and accept PR for it.
