[python] Bug w/ np.array Quaternion parsing

```py
q_B_ECI = Quaternion(np.array((0.0, 0.0, 0.0, 1.0)), Quaternion.Format.XYZS)
```

returns a `[0.0, 0.0, 0.0, 0.0]` quaternion.

Seems to be due to a faulty `np.array -> Vector4d` conversion.

Workaround is to use:

```py
q_B_ECI = Quaternion.XYZS(0.0, 0.0, 0.0, 1.0)
```

instead.
