New Different map cooldown for Different maps

[Fakebailsong]

Most maps share the same cooldown, which is unfair for some extremely difficult and lengthy maps.Especially in these past few days, there have been almost daily occurrences of ze_best_Korea, which has led to some players coming almost solely for this map, resulting in the server dying.So the cooldown of the map should be determined based on its difficulty and length，most of which are one-day cooldowns, and the harder the map, the longer cooldown.
These measures are mainly aimed at preventing players from booking difficult and lengthy maps with almost no "punishment".
