revert sink accepting only char* and size_t

 ##Features
-* Very fast - performance is the primary goal (see becnhmarks below).
-* Headers only.
-* No dependencies.
-* Cross platform - Linux / Windows on 32/64 bits.
-* Variadic-template/stream call styles: ```logger.info("variadic", x, y) << "or stream" << x << y;```
-* [Custom](https://github.com/gabime/spdlog/wiki/Custom-formatting) formatting.
-* Multi/Single threaded loggers.
-* Various log targets:
-    * Rotating log files.
-    * Daily log files.
-    * Console logging.
-    * Linux syslog.
-    * Easily extendable with custom log targets  (just implement a single function in the [sink](include/spdlog/sinks/sink.h) interface).
-* Optional async logging .
-* Log levels.
