Momentum

Added Momentum enchantment

• Treasure enchantment found in Jungle Temples, Strongholds, Abandoned Mineshafts, Dungeons, End Cities, and Villager Trades - not available from the enchantment table.
• Mutually exclusive with Efficiency - you can't have both on the same tool.
• Tools enchanted with it will speed up when the same block is mined, only resetting the speed when a different block is mined.
• This does not happen when a block is partially mined, or naturally breaks instantly, though the speed changes accordingly.
• Without Haste 2, no blocks after the first (8 * hardness^0.5) blocks can be instamined - this is around 13 for ores, and 56 for obsidian.
• The rate of speedup is proportional to (2^-hardness), so around 7 for ores and 54 for obsidian to reach instamine (for netherite tier)
