[Enhancement] avoidFirstLastClipping should keep the labels centered

[dbmrq]

I think the avoidFirstLastClipping option should keep the labels centered, like this:

Instead of this:

I can't see why anyone would prefer the last option, which is what happens right now.
This is what I'm doing to achieve what I want:

chartView.xAxis.avoidFirstLastClippingEnabled = false
let left = 10 + 3 * CGFloat(chartDataPoints.first!.characters.count)
let right = 10 + 3 * CGFloat(chartDataPoints.last!.characters.count)
chartView.setExtraOffsets(left: left, top: chartView.extraTopOffset, right: right, bottom: chartView.extraBottomOffset)

So my offsets are increased by three times the number of characters in the respective label.
This is working fine, but since there already is an avoidFirstLastClipping method, I think it should do all that for me. (Maybe by considering the width of the labels and increasing the offset by half of it?)

Seems to me like you are choosing a very specific value for your offsets.
And avoidFirstLastClipping is doing something very specific, which is avoid being clipped, by sliding the values even while scrolling the chart, which provides for smoother experience.

Not everyone wants the labels to bleed out of the content bounds, which can cause two labels being rendered on top of each other.

So, you have those extraOffsets for those kind of situations where you want to do something a little different :-)
