Tensorneko

Features:

- The codes which do not require `PyTorch` and `PyTorch_Lightning` have been moved to an independent library `tensorneko_util`, but the previous API is not changed.
- You can use this new library with `pip install tensorneko_util`

Fix:

- `tensorneko.util.identity` function now can process the single argument.
- `tensorneko.io.write.video.to` now requires argument `audio_codec` to correctly save video if the argument `audio` is provided.

Features
- Add pickle friendly identity function `tensorneko.util.identity`
- Add wrappers for matplotlib `plot` and `imshow`

Fix:
- The `matplotlib` and `seaborn` requirements now are optional
- Align the text reader default call to `of`

Features:
- Several defined colors for visualization, and a seaborn palette with these colors.
- Add fast implementation based on `Pytorch` to speed up the `resize_video`.

Fix:
- Fix the tooltip line break in LineChart.

Features:
- Now the program will warn when the signature of a `dispatch` function is overridden.
- `View` can get the components by`View[name]`
- Add `dispatch.of(*types)` for manually registering types
- Add `ref` for Ref type wrapper for primitive types
- `Variable` and `ProgressBar` can bind to `Ref`.
- `LineChart` for web watcher visualization

Fix:
- `dispatch` now can support class methods

Features:
- Add `View.add_all()` which can add all previously defined components to the view.
- `dispatch` for multi-dispatch functions.

Features:
- `View.add` uses vararg can add multiple components
- `write.text.to_json` now supports the object annotated by `json_data`

Fix:
- Fix the web watcher components constructors.
- Fix `iou_1d` return type annotation.
