strange datatype of unique_edge_size()

[maximelucas]

Running

H = xgi.load_xgi_data("email-enron")
xgi.unique_edge_sizes(H)

yields

[np.int64(1),
 np.int64(2),
 np.int64(3),
...
 np.int64(36),
 np.int64(37)]

I don't remember these elements being np.int64. There's probably nothing wrong with it but it looks unnecessary.
This might be due to the new numpy version 2.0?

Yes, that's correct! If you want to make a quick PR casting the values to int and adding a short test confirming the data type, I'll approve it!
