gd_framenum_subset64 — perform a reverse look-up on a monotonic Dirfile field, with largefile support.

       This version of gd_framenum_subset(3) uses a 64-bit offset type (gd_off64_t), where one is available, re‐
       gardless  of  the size of off_t.  It is only guaranteed to be available if GD_64BIT_API is defined before
       including getdata.h.

       If  off_t  is  a  64-bit  type,  this  function  will  the  same  as  gd_framenum_subset(3).   Otherwise,
       gd_framenum_subset(3) will be a version of this function which uses a 32-bit off_t.
