Setup real dashcam logging

This project is to maximize the usable dashcam storage space on a comma 3X. Currently, it's tuned for maximum training/debuggability. We should be able to tradeoff a bit of that for a great dashcam experience.

`.hevc` and `rlog` are needed for training and debugging, but they also take up most of the device's storage. They are overkill for dashcam purposes, but the current `qcamera` isn't quite sufficient either.

Some concrete TODOs
* deleter: setup two classes of files "dashcam" and "training"
* deleter: prioritize "dashcam" segments
* logger: bump up `qcamera` size to be great dashcam footage
* logger: setup `qcamera` streams for the wide and driver cams

---

Here's the current size breakdown:
```bash
2.2M qcamera.ts
2.2M qlog
56M rlog
72M dcamera.hevc
72M fcamera.hevc
73M ecamera.hevc
```

Start by locating the deleter and logger components responsible for qcamera, rlog, and the camera streams, then review how storage usage is currently prioritized. The issue identifies separate dashcam and training file classes, dashcam prioritization, larger qcamera footage, and wide and driver camera streams as the target. Done means these four behaviors work together within the comma 3X storage constraints.
