[FEATURE] hub.auto for audio and video htypes

## 🚨🚨 Feature Request

- [ ] Related to an existing [Issue](../issues)
- [ ] A new implementation (Improvement, Extension)

### Is your feature request related to a problem?

Extend hub.auto to enable ingesting audio and video data. Take a look at [ingesting image datasets](https://github.com/activeloopai/Hub/blob/main/hub/auto/unstructured/image_classification.py) for a start.

### Description of the possible solution

Adding a video_ingestion.py file to hub/auto/unstructured with necessary changes would work. But this might mean rewriting a lot of code as in [image_classification.py](https://github.com/activeloopai/Hub/blob/main/hub/auto/unstructured/image_classification.py)

### An alternative solution to the problem can look like

To avoid this, a general class could be written and used as base class for image, audio and video.
