fdo#70798 Add new Excel functions, move from add-in module?

Hi Eike,

>It seems we'll need a genereal plan how to handle the functions that Excel newly introduces but are in fact implementations of ODFF under a new name. Also various of the statistic functions you implemented match that criteria..

>As I wanted to come up with a renaming plan for the FLOOR/CEILING problem anyway I may as well think about this.. seems related.

Yes, it does need some action.
I will leave ERF, ERFC, NETWORKDAYS and WORKDAY for the moment and start on AGGREGATE, which is a beast.
