Overlapping labels on pie chart

* [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 use Charts to create a pie chart on iOS (from 12 to 15).

## What did you expect to happen?

I expect the labels to be spaced out enough to be readable.

## What happened instead?

The labels are overlapped when the values are similar.

Sometimes I also have the issue mentioned on #4488 .
