API support for Composite charts Completed

Request for adding API support for Composite charts.

Currently GemBox.Spreadsheet supports Composite charts (charts with mixed data series type) only through preservation.
This means that these elements are preserved so we don't lose any relevant workbook information when loading and saving to an XLSX format, but they are not directly supported by GemBox.Spreadsheet API.

The following link is a demonstration sample of preserving unsupported Chart types when reading from XLSX file and writing to XLSX file:

More information about GemBox.Spreadsheet's preservation can be found on the following link:

This would be a valuable add to the toolkit. We have some scenarios that are valuable to have a bar chart with 1 or 2 line charts for showing some averages.

I agree, many of the charts I have to produce are composite, so being able to do this would be invaluable.
