Support proper bond types in `connect_via_distances()`

[padix-key]

Currently biotite.structure.connect_via_distances only returns the atom connectivity of a given molecule, i.e. all bonds are BondType.Any. However, this method allows to estimate proper bond orders from atom connectivity, which could be used to make connect_via_distances() actual bond types.

• Implement the linked algorithm as new function
  • Probably an implementation in Cython or Rust (Introducing Rust code into Biotite #688) is advisable
  • Ensure that the function can be cancelled or has something like a max_results parameter to limit run time (e.g. in contrast to the RDKit implementation (DetermineBonds causes a hard freeze for certain Chem.Mol inputs rdkit/rdkit#7922))
• Make connect_via_distances() (by default) use this function
