A forge version of Covenant_Turtle's Mining Cool Down Fix
By default, the Minecraft client has a hard-coded delay of (5 ticks) between break a block and starting to break another, unless your total mining speed would allow you insta-mine it, as per the following wiki article: https://minecraft.wiki/w/Breaking#Instant%5C_breaking
This mod simply sets that delay to 0, allowing you to break multiple blocks much faster than before, without affecting the time it takes to break a single block.
However, it is handled this way in vanilla to avoid accidentally mining too many blocks if your mining speed is high enough. This mod also introduces a new enchantment that limits your mining speed to (1 + level) ticks.
