Augly

Changes

Audio:
- New augmentations: `loop`
- Efficiency improvements: made `high_pass_filter` & `low_pass_filter` ~97% faster by using `torchaudio`

Image:
- New augmentations: `skew`
- Added bbox computation helper `spatial_bbox_helper` to make it easier to add new image augmentations & automatically compute the bounding box transformations (e.g. see how we used this for `skew` [here](https://github.com/facebookresearch/AugLy/blob/main/augly/image/functional.py#L2430))
- Efficiency improvements: made `resize` ~35% faster by defaulting to bilinear interpolation

Text:
- Allow multi-word typo replacement
- Efficiency improvements: made `contractions`, `replace_similar_chars`, `replace_similar_unicode_chars`, `replace_upside_down` ~40-60% faster using algorithmic improvements

Video:
- Efficiency improvements: made 30 of the video augmentations faster using [`vidgear`](https://github.com/abhiTronix/vidgear) (a new dependency we added in this release) to execute `ffmpeg` commands using higher compression rates (e.g. `hflip` 75% faster, `loop` 85% faster, `remove_audio` 96% faster, `pixelization` 71% faster)

Overall:
- Modified internal imports to be Python 3.6-compatible
- Added error messages to unit tests for easier debugging
- If you want to see a full report benchmarking the runtimes of all AugLy augmentations versus other libraries, keep an eye out for the AugLy paper, which will be up on Arxiv in January!

Text
- New augmentations: `swap_gendered_words`, `merge_words`, `change_case`, `contractions`
- Allow for kwarg overriding in `__call__()` for all augmentations
- Exposed `typo_type` param in `simulate_typos` aug
- Added `ignore_words` param to `replace_words` & `swap_gendered_words`

Video
- New augmentation: `augment_audio`

Other
- Enforce `black` formatting

- New unit tests: `Compose`, `overlay_image`
- Fixed `color_jitter_intensity`
- Don't modify input image in `overlay_stripes`
- Added metadata arg to `Compose` operator
