How to generate lots of hyperlinks rather fast using ClosedXML library?
I am using [ClosedXML library](https://github.com/ClosedXML/ClosedXML) to generate an Excel containing thousands of hyperlinks using cell's `Hyperlink` property:

```c#
cell.SetValue(text).Hyperlink = new XLHyperlink(url);
```

Such a call takes about 3ms which seems very fast, but this leads to exports taking up to one minute for large exports (10K+ rows). Writing the URL as text in the cell is much faster, but it is not user-friendly (the user has to enter the cell, and press Enter to trigger hyperlink creation).

Is there a method to improve the performance and still get hyperlinks in the exported Excel?
