Position indepentent parameters

[jeduden]

Since fill uses sprintf, parameters depend on the position in the translation.
Sometimes it can make sense to swap the placeholders.

Further providing names to placeholders can help translators to find the right translation.

I have written an additional extension method fillMap that does this:

Here are few statements from the unit-tests:

expect("doesnt need any placeholder".fillMap({"unused": 3}),
            "doesnt need any placeholder");

expect("<placeholder%d> and <placeholder%03d>".fillMap({"placeholder": 3}),
            equals("3 and 003"));

expect("<placeholder>".fillMap({"placeholder": 3}), equals("3"));

expect("<placeholder/>".fillMap({"placeholder": 3}), equals("3"));  /// optional  / to make it look like a standalone html tag. helps with automatic translation tools, that sometime expand <placehoder> to <placeholder></placeholder>. 

expect(() => "some <placeholder>".fillMap({}), throwsFormatException);

expect("<placeholder%d> and <other>".fillMap({"other": 3}, keep: {"placeholder"}),
            equals("<placeholder%d> and 3"));

Would you accept a PR to add this method to your repo ?

I like your idea. And yes, I would accept it.
