AFL-style UI: Add AFL-style UI to the TUI monitor

LibAFL, a library written by Rust, helps people develop a fuzzer tailored to specific needs, but due to the lack of the running status information of LibAFL, we are difficult to grasp some key metrics in a fuzzing campaign. so I propose adding AFL-style UI to the TUI monitor. LibAFL will have an AFL-style UI encompassing some key status metrics such as the status bar, process timing, and so on.
