Keyboard accessibility on edit

Hi @rwieruch  , can you also add keyboard interactions like [MUI-X DataGrid](https://mui.com/x/react-data-grid/editing/) according to these [vai-aria patterns](https://www.w3.org/WAI/ARIA/apg/patterns/grid/)? I think this feature will make react-table-library superior to any other libraries. I hope you don't ignore it.
