update time measurements to reflect the fact that they should be arrays

time_measurements in core_profiles for density and temperature has been modified to align to the IMAS definition. A time should be given to each measurement, for each radial point, since they could have been taken from different diagnostics at different times. This is necessary as the validators routines in IMAS check for this and some functions, for example copying, do not work otherwise.
