Hello,

I am using the latest voxl-camera-server (v1.8.4) with config C17 (https://docs.modalai.com/voxl2-camera-configs/#c-17-tof-tracking-stereo0v9782-and-hiresimx412). The server crashes after 5 seconds. If I disable either the tracking or both of the stereos the server runs. 

Here is the config I cam using:

```
J6_LOWER_SENSOR="pmd-tof"
J6_LOWER_NAME="tof"

J7_LOWER_SENSOR="imx214"
J7_LOWER_NAME="hires"
J7_LOWER_ROTATE="false"

J7_UPPER_SENSOR="ov7251"
J7_UPPER_NAME="tracking"
J7_UPPER_ROTATE="false"

J8_LOWER_SENSOR="ov9782-combo"
J8_LOWER_NAME="stereo"
J8_LOWER_COMBO_MODE="independent"
J8_LOWER_NAME2="stereo2"
J8_LOWER_ROTATE="false"
```

As you can see the only difference is hires imx412 -> imx214, which should not affect anything?

@James-Strawson I believe you worked on this experiment: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-camera-server/-/commit/e74533d51ec31145da4ab57fa6af1e7c9ec5264f

I have also found that using `stereo:ov7251:3:4` instead of `stereo:ov9782:3:4` works.
