Dataset object with easy saving and automatic versioning

## Example

```ts twoslash theme={null}
// @noErrors
// Create a dataset
const dataset = new Dataset({
  id: 'grammar-dataset',
  rows: [
    { id: '0', sentence: "He no likes ice cream.", correction: "He doesn't like ice cream." },
    { id: '1', sentence: "She goed to the store.", correction: "She went to the store." },
    { id: '2', sentence: "They plays video games all day.", correction: "They play video games all day." }
  ]
})

// Access a specific example
const exampleLabel = dataset.getRow(2).sentence;

// Save the dataset
const ref = await dataset.save()
```
