C# Human Readable Ticks with microsecond and nanosecond units

Here's a great modern was in C Sharp code to format Stopwatch Elapsed Ticks to be human readable number including micro and nanoseconds places. It uses StringBuilder (for speed) and Action delegate for string format variability. 

This implementation will leave units (day, hour, ...) parts if they are zero.  Say that microseconds is 0, it will not print 0µs place to save space of output string.
