Readme is incorrect for OrdinalPluralRule

In the Readme, it's mentioned that:

```go
fmt.Println(l.OrdinalPluralRule(21, 0)) // 21st
fmt.Println(l.OrdinalPluralRule(22, 0)) // 22nd
fmt.Println(l.OrdinalPluralRule(33, 0)) // 33rd
fmt.Println(l.OrdinalPluralRule(34, 0)) // 34th
```

But the actual output is:

```go
One
Two
Few
Other
```
