Expand the space for numbers

[DeltaV-1]

[ ] Bug
[yes ] Feature request

CountUp.js version:

```2.4.0

## Description
I would like if there was more space for the numbers, because you can only have 9 digits before it cuts off.

<!-- If this is a bug, provide steps to reproduce the issue. -->
<!-- If this is a feature request, describe the use case. --> So that you can get larger numbers
