feat(logger): Enhance logging functionality with variadic templates for formatted messages

- Added variadic template methods to the Logger class for formatted logging at different log levels (debug, info, warn, error).
- Updated existing logging calls in CustomRobot to utilize the new formatted logging methods for improved readability and consistency.
- Removed the old log method implementation from logger.cpp to streamline the codebase.
