Feature Request: Pie Charts Variable Inner Radius

[barrymichaeldoyle]

It would be epic if there was a way to make a Pie Chart have slices with variable inner radii, currently the donut pie chart has the hole properties which will set the radii for every slice instead of individual slices.

If you are interested to submit a PR, then you need to add arrayOk: true, to hole attribute here:

plotly.js/src/traces/pie/attributes.js

Lines 241 to 251 in a539c88

	hole: {
	valType: 'number',
	min: 0,
	max: 1,
	dflt: 0,
	editType: 'calc',
	description: [
	'Sets the fraction of the radius to cut out of the pie.',
	'Use this to make a donut chart.'
	].join(' ')
	},

Then inside pie/plot.js, you should revisit places .pole is used to read the value. E.g. you could see how this is handled for the pull attribute which is already arrayOk.

Please visit CONTRIBUTING.md for more information.

@archmoj thank you so much! I've pushed changes to the PR. I think I've covered all .hole scenarios. Hopefully correctly :)
