Labels overlapping

Hello,

First of thanks for the library.

The slice labels are overlapping if the slice values are too small. Here is a sample screenshot:

Is it possible to solve this?

It is easily reproducable in Example project by chaging the models in DoughnutDemo.swift to :

        let models = [
            PieSliceModel(value: 0.1, color: colors[0]),
            PieSliceModel(value: 0.2, color: colors[1]),
            PieSliceModel(value: 0.3, color: colors[2]),
            PieSliceModel(value: 99.4, color: colors[1])
        ]
