fpspreadsheet: Add code for detection of date/time cells which are incorrectly written as float by Open/LibreOffice. Implement conditional number formats for all number types (sometimes falsely assigned). Reactivate ignored date test cases for ods-1899, pass. 1904 date mode still faulty, not clear if this will ever pass the test.
