The code has been updated to enhance the way log levels and backtrace information is handled. Changes have been done to ensure the backtrace ignores any calls coming from the LogLib namespace, improving clarity and reducing noise in the log output. Additionally, changes were made to 'colorize' and 'log' methods to adjust the typing of the log level from string to integer, enhancing the consistency of log level usage throughout the code. Removed the Backtrace class that was not serving any purpose after these updates. Tests are also updated to ensure proper functionality."
