Node logging convenience class.
This class is based on the standard UAVCAN message type for logging - uavcan.protocol.debug.LogMessage.
Provides logging methods of different severity; implements two sinks for the log messages:
- Broadcast via the UAVCAN bus;
- Sink into the application via ILogSink.
For each sink an individual severity threshold filter can be configured.

Logs one message. Please consider using helper methods instead of this one.
The message will be broadcasted via the UAVCAN bus if the severity level of the message is >= severity level of the logger.
The message will be reported into the external log sink if the external sink is installed and the severity level of the message is >= severity level of the external sink.
Returns negative error code.

Helper methods for various severity levels and with formatting support. These methods build a formatted log message and pass it into the method log().
Format string usage is a bit unusual: use "%*" for any argument type, use "%%" to print a percent character. No other formating options are supported. Insufficient/extra arguments are ignored.
Example format string: "What do you get if you %* %* by %*? %*. Extra arguments: %* %* %%" ...with the following arguments: "multiply", 6, 9.0F 4.2e1 ...will likely produce this (floating point representation is platform dependent): "What do you get if you multiply 6 by 9.000000? 42.000000. Extra arguments: %* %* %"
Formatting is not supported in C++03 mode.
