Add support for RTD (Real Time Data) function creation

[allanvc]

Thank you for this excellent package. Would it be possible to add support for creating cells with the RTD function?

Example:

form <- 'RTD("rtdtrading.rtdserver";; "ASSET_B_0"; "ULT")'
class(form) <- c(class(form), "formula")
wb <- createWorkbook()
addWorksheet(wb, "RTD")
writeData(wb, sheet = 1, x = form)

In the current version of openxlsx, excel does not recognize the RTD function created in openxlsx.
