No longer possible to set Style with auto updating text
Before `2.6.0`, I did the following:
```typescript
const [formattedDate, timeToNextUpdate] = timeAgo.format(date, style, {
getTimeToNextUpdate: true
});
```
With `>2.6.0`, it is no longer possible to use either `refresh()` or `timeToNextUpdate` together with `style`, as those are the only 3 options:
```typescript
format(date: DateInput, style?: FormatStyleName | Style, options?: FormatOptions): string;
format(date: DateInput, options: FormatOptionsWithGetTimeToNextUpdate): [string, number?];
format(date: DateInput, options: FormatOptionsWithRefresh): [string, () => void];
```
I'd like to update to `2.6.0`, but this prevents me from using it.
