Allow bigint to be passed into `value`

Given `BigInt` is widespread at this point, may be worth updating the type of `value` to accept bigints,

```tsx
const example1 = (
  <>
    <NumericFormat value={100} /* OK */ />
    <NumericFormat value={100n} /* Type Error */ />
  </>
);
```

in the meantime, can easily get around this with,

```tsx
const example2 = (
  <NumericFormat value={(100n).toString()} />
);
```
