Return original data entry in customRowRender

## Expected Behavior
The callback of customRowRender is returning for the first argument one array instead of the original data entry which is key based object

This can be fine, but we need also to get back the original data object key based instead of being converted to array.

That means that if I pass to

```

const COLUMNS = [
{
name: 'name',
label: 'Name',
},
{
name: 'surname',
label: 'Surname',
},
];

const data = [
{
name: 'kristi',
surname: 'jorgji',
}
];

return

```

I expect to be able to get the data object entry exactly with key structure somehow in the customRowRender instead of being in array format like below currently (I am simplifying here, but in real usage is complex data structure nested etc and such option is really needed, getting back in array format is not helpful.
```
[
0 => kristi
1 => jorgji
]
```

## Current Behavior
`customRowRender: (data) => {
console.log(data); // the data here will be array, cannot find any way to get back the original data structure
}`

## Your Environment

"@material-ui/core": "^4.11.1",
"mui-datatables": "^3.7.3",
"@types/mui-datatables": "^3.7.0",
"react": "^17.0.1",

Start at the customRowRender callback and trace how each data entry is transformed before the callback receives it. Compare the current array argument with the original key-based object described in the issue, including nested data. Done means customRowRender can access the original data structure rather than only positional values.
