v1.0.3 brings significant performance improvements. No new features are added.

The log subsystem behavior is now less engaged. Users may still supply their own *log.Logger, however no internal use of any log system occurs by default now. Overzealous internal use resulted in significant performance degradation.

A (pprof) performance analysis was done to guide this pull request. Certain inefficiencies were identified and corrected (largely those involving aforementioned log use).

Code coverage remains 100%. Test times dropped from 0.2s to 0.005s on average.

I also investigated the possibility of reducing calls to append, however due to the nature of how the underlying *stack type is used, this seemed to be more trouble than it would be worth (given the radically improved performance changes mentioned above).

Its OK To Append Sometimes.™️
