`DWaveCliqueSampler` occasionally produces an out-of-range qubit coupling

A per-group-coupling-range test [occasionally fails](https://app.circleci.com/pipelines/github/dwavesystems/dwave-system/738/workflows/e1d31324-dd7a-4619-b28e-4fa485f6b385/jobs/13888) with:

dwave.cloud.exceptions.SolverFailureError: Total coupling -13.000 for qubit 2793 to qubits 1730,1741,1754,1765,1778,1789,1802,1813,2792,2804 is out of range (-13.000 10.000).
```

Coupling values in this case are (on solver `Advantage2_system1.5`):
```
[np.float64(-1.7660377358490567), np.float64(-1.7660377358490567), np.float64(-1.7660377358490567), np.float64(-1.7660377358490567), np.float64(-1.7660377358490567), np.float64(-1.7660377358490567), np.float64(-1.7660377358490567), np.float64(-0.44150943396226416), np.float64(-0.1962264150943396)]
```
with the total sum of:
```
-13.000000000000002
```

So the lower bound of `per_group_coupling_range` (`-13`) is indeed exceeded, but due to float64 precision limits.

Arguably, this edge case should be handled on SAPI side, as the quoted precision is only 3 digits (`-13.000`).
