 * @brief Alias of callback function for progress of a bootloader pipeline task
 * 
 * The progress value passed into the callback function indicates the following:
 * 1) If the value is std::nullopt, this implies the status message is for an asynchronous task or a task in which the current progress is unknown.
 * 2) If the value is between 0 and 1 (i.e., 0 <= progress <= 1), this implies the actual progress of the current task as a percentage.
 * 3) Values not between 0 and 1 (i.e., progress < 0 or progress > 1) are undefined.
