refactor: simplify sleep time functions

The `fn_sleep_time` function has been refactored to remove unnecessary conditions and set a default sleep time of 0.5 seconds. Additionally, four new functions (`fn_sleep_time_1`, `fn_sleep_time_5`, `fn_sleep_time_10`) have been added to provide different sleep times of 1, 5, and 10 seconds respectively. This improves code readability and allows for more flexibility in setting sleep times.
