We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Add icedata to icevision.all
## 🚀 Feature
Currently to train a dataset available with icedata the following two lines are necessary:
```python
import icedata
from icevision.all import *
```

Because icedata already depends on icevision, icevision cannot depend on icedata. **But** I guess we can add icedata as a soft dependency to `.all`, we just have to be sure not to use `icedata` internally in icevision.

--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
--- BEGIN FILES ---
Path: `icevision/all.py`
Content:
```
1 from icevision.imports import *
2 from icevision import *
3
```
