Aim: Return logicals defining the data mode.
The routine declaration is:
subroutine getMode(ev_tab, imaging, timing, redImaging, compTiming)
! ev_tab: handle to the events extension
! imaging: set to True if IMAGING (EPIC) or SPECTROSCOPY (RGS) mode
! timing: set to True if TIMING (EPIC) or HTR (RGS) mode
! redImaging: set to True if REDUCED IMAGING (MOS) mode
! compTiming: set to True if COMPRESSED TIMING (MOS) or BURST (PN) mode
type(TableT), intent(in) :: ev_tab
logical, intent(out) :: imaging, timing, redImaging, compTiming
