The main logging function isn't really suitable for generating inline hexdumps directly from the binary data. There is simply no format string available for converting array data types with just a single printf call. A possible solution would be to require the caller to perform the string conversion before calling the standard logging function. But that's not acceptable, because it doesn't play well with the ability to disable the logging at compile time, requires extra memory and clutters the calling code unneccessary. The new function is a compromise which sacrifices flexibility for simplicity, by using a hardcoded output format with a custom prefix. It's not a perfect solution, but it works well enough for the intended purpose.
