Vault Faster

Minecraft Vault Hunters optimization mod with one goal: make vault world generation faster.
More than 4x performance improvement.

List of changes:

[batchSetBlocks.kt] blocks are placed with optimised algorithm
- skips heightmap updates
- locks chunk only once per section instead of every block
- skips iskallia.vault.core.event.CommonEvents.BLOCK_SET event
[MixinBlockRegistryIndex.java, PartialBlockRegistryIndex.java, IndexedBlock.kt] replaced "string ids"/ResourceLocations of blocks and PartialTiles with "numerical ids"/registryIndex
[TileMapper.kt] added tile mapper; algorithm for minimizing number of applicable iskallia.vault.core.world.processor.tile.TileProcessors by storing them in multimap indexed with numerical id of a block
cached some values
[NoBiomeDecorations.java] removed biome decorations

Performance on my system (# of chunks generated in 50 seconds):
