Updated README.md

Added the NanoLog dissertation link and stated that the system
currently only works for Linux-based systems at the moment.

 How it achieves this insane performance is by extracting static log information at compile-time, only logging the dynamic components in runtime hotpath, and deferring formatting to an offline process. This basically shifts work out of the runtime and into the compilation and post-execution phases.
