feat: add chart size type overrides

[markov00]

Summary

fix #177

Add multiple override types for <Chart> size props.

The size parameters now accept ChartSize:

type ChartSize = number | string | ChartSizeArray | ChartSizeObject;
type ChartSizeArray = [number | string | undefined, number | string | undefined];
type ChartSizeObject = {
  width?: number | string;
  height?: number | string;
}

The default value for an undefined parameter is 100%.
