range does not work with datetime

[dasergatskov]

octave:2> pkg load datatypes
octave:3> t0 = datetime(2025,5,7,0,0,0)
t0 =
  datetime

   07-May-2025
octave:4> t1 = datetime(2025,5,8,0,0,0)
t1 =
  datetime

   08-May-2025
octave:5> dt = hours(1)
dt =
  duration

   01:00:00
octave:6> xtime_range = (t0:dt:t1)
error: max_stack_depth exceeded
octave:7> 

Or even just:

octave:1> pkg load datatypes
octave:2> t0 = datetime(2025,5,7,0,0,0)
t0 =
  datetime

   07-May-2025
octave:3> t1 = datetime(2025,5,8,0,0,0)
t1 =
  datetime

   08-May-2025
octave:4> xt = t0:t1
error: max_stack_depth exceeded

Fixing this is rather complicated, because datetime points are not stored in a single variable as a property of the datetime classdef. Most likely, I will need to implement a compiled function to deal with datetime arithmetic, which will require some time and effort.
On the bright side, I spotted an inconsistency when calculating range in duration objects, which has been fixed with release-1.0.3.
