Yet another Fast and Efficient logging framework. The goal is to be nanosecond level fast with extensibility (inspired by loggers such as spdlog, nanolog, and fmtlog and heavily influenced by the formatting used in fmtlib and <format>). This uses a built-in formatter that can be swapped out for <format> or fmtlib if desired.
