v0.8.2

## Paragraphs
Now you can label structured text in simple json format. Introducing `Paragraphs`!
It requires array of phrases, defined as object with two required fields:
first one for author (set by `nameKey`, "author" by default) and second one for text itself
(set by `textKey`, "text" by default). For better appearance use `layout="dialogue"`.

#### Audio pre-listening
Also you can attach audio for these phrases by `audioUrl`.
It uses optional fields in phrases' objects: `start` and `end`/`duration` in seconds,
linking phrases with according part of audio.

## Taxonomy
`<Taxonomy>` is a new control tag wrapper that allows you to build a nested choices structure - a multi-class classification tree. The usage is quite intuitive:
```xml
  <Taxonomy name="" toName="text">
    <Choice value="Archaea" />
    <Choice value="Bacteria" />
    <Choice value="Eukarya">
      <Choice value="Human" />
      <Choice value="Oppossum" />
      <Choice value="Extraterrestial" />
    </Choice>
  </Taxonomy>
```

## Undo/Redo/Reset
Now you can see the current state of your actions history — is it possible to undo/redo.
Also reset can be undone.
Both `cmd+z` and `ctrl+z` are working now.

## TextArea regions
Improve text comments, especially multiline ones — they appears much better than before,
you can add them by `shift+enter` or cancel editing by `escape`.
Also you can delete classification comments with trash bin icon next to it.
And they will back to Regions list soon.

## Machine Learning Backend Features

* New ML backend for chatbot responses generation from `<Paragraphs>` (powered by [HuggingFace's GPT2](https://huggingface.co/models?filter=gpt2))

* Project local path is accessible on ML backend API - in case you want to read uploaded images/audio directly from disk

## New UI settings
* Line numbers for Text/Paragraphs
* Select region after create for better per-region labeling

## Project sharing

Now it's possible to move and share the entire project folder and start annotations from any other path

## Fixes

* Display spinner while loading heavy TimeSeries
* Return back `onEntityDelete`/`onEntityCreate` callbacks
* Various fixes Image regions stability
* Performance improvements for large regions numbers
* Task IDs are now safely restored, even if you break or delete `source.json`
* Get rid of some packages dependencies error
* Export to VOC with broken image paths
* Windows path for ML backend https://github.com/heartexlabs/label-studio/issues/500
