I'm not a big fan of having a class named `Style` as it is commonly used in
business logic. (Yes, its an inner class, but I still think the potential
for annoyance is high). java.time.* has `TextStyle`, but I don't think it
can be reused here. Maybe the class should be honest and called
NumberFormatStyle (as a top level class).

More generally, the API does not allow the caller to take control of the
text, for example to use "mil" as a suffix for million. eg Think of this
method in java.time.* -
