 * Morse Code Timing Utilities
 *
 * This module provides functions for calculating Morse code timing parameters.
 *
 * Farnsworth Timing:
 * Farnsworth timing is a method of sending Morse code where the individual characters
 * are sent at a higher speed (wpm), but the spacing between characters and words is
 * increased to achieve a lower effective speed (fwpm). This technique was developed by
 * Russ Farnsworth (W6TTB) to help students learn Morse code more effectively.
 *
 * The idea behind Farnsworth timing is that learners can become accustomed to hearing
 * and recognizing characters at higher speeds, while the extended spacing gives them
 * more time to process each character before the next one arrives. As proficiency
 * increases, the spacing can be gradually reduced until standard timing is achieved.
 *
 * In standard Morse timing, characters and spaces are proportional to the dit length.
 * In Farnsworth timing, the characters maintain the same internal timing as they would
 * at the higher speed, but the spaces between characters and words are extended.
