Crash while selecting data point in zoomed state

* [x] I've read, understood, and done my best to follow the [*CONTRIBUTING guidelines](https://github.com/jjatie/Charts/blob/master/CONTRIBUTING.md).

## What did you do?

ℹ I zoomed the charts and made a selection to one of the data point.

## What did you expect to happen?

ℹ The delegate method with selected coordinates should be called.

## What happened instead?

ℹ Crash happed.

ℹ Please link to or upload a project we can download that reproduces the issue.

Start at AxisRendererBase.swift:125, then trace the NaN bounds through XAxisRenderer.swift and BarLineChartViewBase.swift:332. Reproduce the reported zoom-and-selection flow if possible; done means selection calls the delegate with coordinates without crashing during axis computation.
