added StreaminCell.getRawContents()

@monitorjbl it's possible to merge and release this?

Our project upgraded xlsx-streamer version from 1.0.0 to 2.1.0 for fixing vulnerabilities, but we found out StreaminCell.getRawContents() has been removed. Will this method be added back or provide a way to replace it in the future?

could you use 'public double getNumericCellValue()' on Cell instead?

Thanks for reply, I hope to get the 'rawContents' and convert it to 'String', use like this: '(String) streamingCell.getRawCotents()'.
Can I use 'public String getStringCellValue()' instead?
