DurationPrinter class

Prints Duration objects in custom ways.

For example, to print dates in the format YYYY-MM-DD call the constructor and configure the printer as such:

 final printer = DurationPrinter((builder) => builder
  ..part(TimeUnit.year, printer: FixedNumberPrinter<int>(padding: 4))
  ..literal(':')
  ..part(TimeUnit.month, printer: FixedNumberPrinter<int>(padding: 2))
  ..literal(':')
  ..part(TimeUnit.day, printer: FixedNumberPrinter<int>(padding: 2)));
print(printer(const Duration(days: 1234, seconds: 56789)));  // 0003-04-19
