Sugestion: Add libKISSlog in the log library section

[libKISSlog](https://github.com/pibara/libKISSlog) - trivial light-weight C++ template library that was designed and written according to the KISS ( Keep It Simple & Straightforward) principle. Uses a fully singleton-free and macro-free design and provides an interface based on streams, extendability and dependency injection. [Boost software licence]
