Is it possible to seed augmentations

## 🚀 Feature
Checked the code and it doesn't seem possible to seed the augmenters.

## Motivation

To reproduce the same augmented test sets.
Also to (deterministically) augment small test sets.

## Pitch

Adding the possibility to seed augmenters like `My_Augmenter(**my_params, seed=42)` which would make reproducible augmentations. Not always the same for all the batch but always in the same order in a reproducible manner.

## Alternatives

Don't use augmentation in the test set.

## Additional context
I'm working with text, and I would like to augment a test set but the idea also apply to images and audio.

Thanks in advance and thanks a lot for this nice library !

Start by surveying the augmenter implementations for text, image, audio, and video, along with how randomness is currently handled. Define the reproducibility expectations for a seed across batches and modalities; the work is done when augmentations can be seeded consistently and the behavior is covered by tests.
