numpy > 2.0 produces unexpected results

[jmorese]

When numpy > 2.0 installed we found unexpected behavior in resample and set_index.

Test one:

 a = tp.event_set(
     timestamps=[1.5, 5.0, 8.0, 9.0],
     features={"f1": [1.0, 2.0, 3.0, 4.0]}
 )
 b = tp.event_set(timestamps=[-1.2, 1.6, 6.0, 10.0])
 c = a.resample(b)
 c

Expected: [ nan, 1, 2, 4]
Obtained:

Test two:

 a = tp.event_set(
     timestamps=[1.5, 5.0, 8.0, 9.0],
     features={"f1": [1.0, 2.0, 3.0, 4.0], "f2" : ["a", "a", "b", "b"]}
 )
 a.set_index('f2')

Expected: Same event set with an index.
Obtained:
