296 by @ketbra introduced date support for xlsb but it fails to handle the built-in formats in case there are no custom-formatted cells present as in this case, the BrtBeginFmts section is missing (which is where the built-in date formats are currently being handled).
To reproduce: run date_xlsb test, but using the attached file instead of date.xlsb.
