Allow usage of custom color for each bar on ProgressChart

[glibas]

Adds extra property 'colors' to ProgressChart data

e.g.

const progressChartData = {
  labels: ["Swim", "Bike", "Run"], // optional
  data: [0.2, 0.5, 0.3],
  colors: ["#dfe4ea", "#ced6e0", "#a4b0be"]
};

can be switched on by setting withCustomBarColorFromData to true

e.g.

 <ProgressChart
         data={progressChartData}
         width={width}
         height={height}
         chartConfig={chartConfig}
         style={graphStyle}
         hideLegend={false}
         withCustomBarColorFromData={true}
/>
