Returning Duplicate Neighbors

[ArmanJR]

It's weird, but I get completely different results when running the first example of the documentation:

import numpy as np
from voyager import Index, Space

# Create an empty Index object that can store vectors:
index = Index(Space.Euclidean, num_dimensions=5)
id_a = index.add_item([1, 2, 3, 4, 5])
id_b = index.add_item([6, 7, 8, 9, 10])

print(id_a)  # => 0
print(id_b)  # => 1

# Find the two closest elements:
neighbors, distances = index.query([1, 2, 3, 4, 5], k=2)
print(neighbors)  # => [0, 1]
print(distances)  # => [0.0, 125.0]

0
1
[0 0]
[0. 0.]

It seems when querying, a neighbor is being considered more than once.
