SAS date formats (YYMMDDxw) not converted #324

I have come upon SAS files where the date format string is not purely YYMMDD but a bit more detailed - YYMMDDN in my case. These are not converted to R dates by haven but left as doubles.

It appears that there are multiple date formats in SAS:

However these extended ones are not considered:

else if (format == "YYMMDD") return HAVEN_DATE;

Would it be possible to load these extended formats as dates as well?

Looks like we should switch to hasPrefix() here because all of the date formats can be followed by optional parameters.
