DOC: Incorrect description of 'coords' and 'other_coords' in 'order.nearest_neighbors' and 'order.k_nearest_neighbors'

[aritra-mukhopadhyay]

Problem description:

These two descriptions should be interchanged:

coords (np.ndarray of shape (N,3)) – Array of coordinates/points to search for neighbors.

other_coords (np.ndarray of shape (M,3) or None, optional) – Array of points to search for neighbors of. The default is None (use coords).

Suggested content improvement:

Should read:

coords (np.ndarray of shape (N,3)) – Array of points to search for neighbors of.

other_coords (np.ndarray of shape (M,3) or None, optional) – Array of coordinates/points to search for neighbors. The default is None (use coords).
