Extend the logger to support coloring messages. The log level is colorized with per-level colors, and the category with a fixed color. This makes the log output more readable. Coloring is enabled by default when logging to std::cerr, and can be disabled by setting the LIBCAMERA_LOG_NO_COLOR environment variable. When logging to a file with LIBCAMERA_LOG_FILE, coloring is disabled. It can be enabled for file logging using the logSetFile() function.
