-#### Mapped diagnostic context (MDC)
-MDC is a map of contextual information that can be used to enrich log messages.
-It is a map of key-value pairs that can be set on a per-thread basis since it is stored in thread-local storage.
-```c++
-#include "spdlog/spdlog.h"
-#include "spdlog/mdc"
-...
-spdlog::mdc::put("key1", "value1");
-spdlog::mdc::put("key2", "value2");
