Header/Footer Font styling

[OssianEPPlus]

In the current implementation of HeaderFooter users must apply formatting codes themselves rather use the Font and or RichText style pattern used everywhere else. If possible we may want to have the interface be the same as elsewhere in Epplus.

Basically instead of having the user input
worksheet.HeaderFooter.OddHeader.CenteredText = "&24&U&\"Arial,Regular Bold\" Inventory";
It would be nice and more intuitive if one could do something like:
worksheet.HeaderFooter.OddHeader.CenteredText.Font.Bold = True;
worksheet.HeaderFooter.OddHeader.CenteredText.Font.Size = 24;
worksheet.HeaderFooter.OddHeader.CenteredText.Text = "Inventory";
