/**
 * Calculates the yAxis value-range depending on a given timeseries-array each containing data-points.
 * Depending on the passed chart-variant, the value-range can be:
 *  - non-stacked (e.g.: line): range from min value to max value across all datapoints for all series
 *  - stacked (e.g.: area): range from the sum of all min values to the sum of all max values across all datapoints grouped by timestamp
 *
 * @param series - The series that serves as base for calculating the value-range of the datapoints.
 * @param variant - The variant (or type) of the Chart, e.g. 'line', 'area', 'bar', 'band'.
 * @param leftAxisMetadata - metadata set from previous geometries on the left axis
 * @param rightAxisMetadata - metadata set from previous geometries on the right axis
 * @param seriesMap - series metadata map
 * @param datapointsMap - data points metadata map
 * @returns an object containing [key] as unit of the scale and value as the value-ranges for the given series depending on the chart-variant
