Incorrect v8 xpt files

[DirkDeWachter]

BUG.
In version 8 xpt files, the record count is missing in the OBSV8 header. As a result SAS 9.4 opens the xpt-file and creates the dataset with all the variables but does not read any records.

Source file
haven/src/readstat/sas/readstat_xport_write.c line 458
Function
xport_write_obs_header_record

Solution:
The function should use xport_write_header_record_v8 in the return statement in stead of plain xport_write_header_record
