🔨 Refactor

Made the value property of data items optional for Bar and Line/Area charts. Added null safety types for internal calculations, while the <BarChart> and <LineChart> components exposed by the library will be capable of accepting null/undefined values as data items, internally it will be conerted to respective nullSafe type after handling the null values (by interpolatio or replacing with 0).
Below are the exposed types and their corresponding null afe types-

Chart Type	Type of data prop	Corresponding null safe type
BarChart	barDataItem[]	barDataItemNullSafe[]
LineChart	lineDataItem[]	lineDataItemNullSafe[]
LineChart with dataSet	DataSet[]	DataSetNullSafe[]

This refactor fixes the below type-related issues-

1. #787
2. #781

v1.4.47

🎉 1.4.47

✨ Features added-

1. Added the properties hidePointerForMissingValues and hidePointerDataPointForMissingValues to the PointerConfig object. In case there are data items with missing/undefined/null values the library interpolates those values. But if you don't want the pointer to be displayed for such values, you can set the hidePointerForMissingValues property to true. Its default value is false. When hidePointerForMissingValues is set to true, hidePointerDataPointForMissingValues automatically becomes true, unless otherwise specified. See #881

🐛 Bug fixes

1. The vertical strips shown by using the showStrip property were always shown over the data points, but now they will be shown beneath the data points. This behaviour can be reversed by using the stripOverDataPoints prop.

v1.4.46

🎉 1.4.46

Added the prop named stripOverDataPoints to Line charts. If set true, the vertical strip appears over the data points, else it appears beneath the data points. See #877
