stream rows read data enhancement

[fudali113]

Expect to be able to get more content when streaming reads the data:

such as:

• get cols info
• get row cells attrs
• get mergeCells info
• get dimension info
• get sheetViews info

etc.

Thanks for your issue. The aim of creating the stream mode functions was not re-provide each function as the normal mode functions, it was just used to process the workbook with the huge amount of data, we need to evaluate if those features suit a typical scenario.

The problem I am facing now is that obtaining relevant information of sheet is a rigid requirement; When we encounter large files, we can reduce the memory overhead by streaming row data, but when we get other sheet information, we can only downgrade to full memory load.

Because these information can be obtained without performance loss during stream reading, it is hoped to enhance stream reading to obtain relevant information.
