Enchantment of dueling

Dueling would be an enchantment that could be put on a sword or spear. (For java) Dueling 1 would negate the cooldown of a weapons initial hit and give the player a speed boost for 1.2 seconds, allowing them to get a second hit. To balance it, each level to the enchantment would give it a shorter cooldown, dueling 1 would have a cooldown of 20 seconds, while dueling 2 could allow for a speed boost for 1.5 seconds and a cooldown of 10 seconds. (For bedrock) The enchantment should only apply to spears.
