add verticalHeight prop for DayPicker

[ingiulio]

Addresses #632

👋

These changes allow the user of DayPicker to specify a vertical height (applied only when on vertical orientation), while keeping the current behavior (an arbitrary size) as the default if no height is specified.

This is actually slightly different than what the issue's title suggests, but imho it seems easier for the user to just have full control on the height rather than trying different "factors". Open to different opinions obviously!

Seems reasonable to me. Should we pass the prop through the DateRangePicker/SingleDatePicker components as well?

[ljharb]

should this be a nonNegativeInteger?

[ingiulio]

sounds good, I can't think of a case where it would in fact make sense to use a negative height 🤔

[ingiulio]

@majapw ok! I'll add it there too.

Btw, is the Changes unknown [etc] message from coveralls something new?

[ljharb]

@ingiulio try rebasing on the latest master, on the command line?

This PR will be ready to go once you can set the verticalHeight prop in the SingleDatePicker, DateRangePicker, DayPickerSingleDateController, and DayPickerRangeController.

I also reran the pending test.

[ingiulio]

Done, thank you!
Do you think the stories for SingleDatePicker and DateRangePicker are useful? I guess they help verify the props are passed through properly, but if they don't add much value please let me know and I'll just remove them.

I think more examples is always a great idea! :) If we were to add a visual diffing tool like https://github.com/Galooshi/happo or something, every example we've already written would add that much more. I'm pretty happy with this.

Could you also add verticalHeight: nonNegativeInteger to the DateRangePickerShape and SingleDatePickerShape files? :)

After that, I'll merge this in. :)
