Report disk average I/O in microseconds/nanoseconds (issue #89)

Very fast drives might show 0.0 ms as the average I/O time. Therefore, average I/O unit will be adapted to the smallest possible unit. Due to the use of microseconds (abbreviates to a multibyte character), the ncursesw library is used instead of ncurses library (the latter calculates the number of characters in a wrong way).
