C# Human Readable Ticks with microsecond and nanosecond units

Here's a great modern way to format C# 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 out zero units parts.  Say that microseconds is 0, it will not print 0µs place to save space of output string.
