Allow customizing the key property type

[danielpza]

Why? This fails:

const [selected, setSelected] = new Set<string>([])

<DataGrid selectedRows={selected} onSelectedRowsChange={setSelected} />

because onSelectedRowsChange was expected to receive all the properties React.Key has, eg number, which is not possible/desired.

@amanmahajan7 can you comment on if is going to be accepted or if there a problem with the PR?

I think it's a good idea.
Can you please also add the generic to the default export, it's at the end of DataGrid.tsx.

Please also add the generic to the default export at the end of DataGrid.tsx, it won't be usable otherwise.
