Expanded rows should be controllable

As requested here.

Gist:

The rowExpansion property object should also include:

• records → currently expanded records
• onChange → callback fired when currently expanded records change: onChange: (records: T[]) => void

Done in v1.7.9. Can be used like this:

<DataTable
  // ...
  rowExpansion={{
    // ...
    expanded: {
      recordIds: expandedRecordIds,
      onRecordIdsChange: setExpandedRecordIds,
    },
  }}
/>

Full working example in Controlled mode section of this page.
