This commit includes the following updates:
- Added a new 'pprof' flag to the command-line arguments in main.go. This flag allows the user to specify a file name for writing CPU profile information, enabling performance analysis.
- Implemented functionality to start CPU profiling in the 'Before' function. If a file name is provided via the 'pprof' flag, the function creates the specified file and begins CPU profiling.
- Added an 'After' function to stop CPU profiling once the program execution is finished.
These changes provide a way to analyze the CPU usage of the 'lotus-shed' application, which can be valuable for performance tuning and optimization.
