Update to 1.20 (alternative option)

This PR makes minimal changes in order to be as easy as possible to merge. However, the main reason I've created this PR is PR #26 will only work with vanilla logs. In that sense, this is a more correct implementation (as much as is possible since Material was removed). Instead of hard-coding some vanilla log types, this PR uses the minecraft:logs block tag, which must work for any mod using vanilla's LeavesBlock without significant modification, because that is the tag used in vanilla decay.

It is possible some mods with a custom leaves implementation may not work (may not add their logs to minecraft:logs), but I did not find any such mods in a brief survey of major Fabric biome mods. I don't think we need to worry about this, but if you want an implementation that should work in roughly any case the Material-based implementation did, the following is fairly equivalent. (I've noticed some mods seem to take a lot of liberties in their mapping of block sound group to wood type, so this doesn't assume bamboo isn't used for real logs or nether can't be a tree with leaves.)

    private void afterBreak(World world, BlockPos pos, BlockState state, PlayerEntity player, CallbackInfo info) {
        if (!world.isClient && (state.getBlock() instanceof PillarBlock)) {
            BlockSoundGroup soundGroup = state.getSoundGroup();
            if (state.isIn(BlockTags.LOGS) ||
                    BlockSoundGroup.WOOD.equals(soundGroup) ||
                    BlockSoundGroup.NETHER_WOOD.equals(soundGroup) ||
                    BlockSoundGroup.CHERRY_WOOD.equals(soundGroup) ||
                    BlockSoundGroup.BAMBOO_WOOD.equals(soundGroup)) {
// ...

The second set of changes is a little more intrusive, but necessary for Terraform API leaves blocks to work. It also makes breaking waterlogged leaves work properly.
