Dear hiphive developers & users

I wanted to generate structures in three different methods called standard rattle, Monte Carlo modified rattle procedure (MC-rattle) and Superposition of normal modes (phonon-rattle).

to this end I have followed the tutorial in advanced topics but I faced an error in monte carlo step which I pasted below:

```
Exception Traceback (most recent call last)
Cell In[8], line 3
1 # Monte Carlo rattle
2 print('Monte Carlo rattle')
----> 3 structures_mc_rattle = generate_mc_rattled_structures(
4 supercell, n_structures, 0.25*rattle_std, min_distance, n_iter=20)
5 write('structures_mc_rattle.extxyz', structures_mc_rattle)
File ~/anaconda3/envs/phono3py/lib/python3.9/site-packages/hiphive/structure_generation/rattle.py:112, in generate_mc_rattled_structures(atoms, n_structures, rattle_std, d_min, seed, **kwargs)
110 atoms_tmp = atoms.copy()
111 seed = rs.randint(1, 1000000000)
--> 112 displacements = mc_rattle(atoms_tmp, rattle_std, d_min, seed=seed, **kwargs)
113 atoms_tmp.positions += displacements
114 atoms_list.append(atoms_tmp)
File ~/anaconda3/envs/phono3py/lib/python3.9/site-packages/hiphive/structure_generation/rattle.py:217, in mc_rattle(atoms, rattle_std, d_min, width, n_iter, max_attempts, max_disp, active_atoms, nbr_cutoff, seed)
215 atoms_rattle[i].position -= delta_disp
216 else:
--> 217 raise Exception(f'Exceeded the maximum number of attempts for atom {i}')
218 displacements = atoms_rattle.positions - reference_positions
219 return displacements
Exception: Exceeded the maximum number of attempts for atom 0
```

please help me to understand and solve the error?
