timeSelector: Add support for -newTimes option

//- Return the set of times selected based on the argList options
    //  including support for \b -newTimes in which times are selected
    //  if the file <fName> does not exist in the time directory.
    //  Also set the runTime to the first instance or the
    //  \c constant/ directory if no instances are specified or available
    static instantList select
    (
        Time& runTime,
        const argList& args,
        const word& fName
    );

This is experimental functionality and currently on test in the yPlus
post-processing utility.
