Add support to Java Edition 1.15.1

Is your feature request related to a problem? Please describe.
Minecraft 1.15.1 is out, it added a few blocks and items and changed how the biomes are stored in the chunk format.

Describe the solution you'd like
Blocks:

• Map the power state from bells
• Map bee_nest
• Map bee_nest rotation and honey level
• Map beehive
• Map beehive rotation and honey level
• Map honey_block (with correct ID)
• Map honeycomb_block (with correct ID)

Items:

• Map bee_spawn_egg
• Map honeycomb (with correct ID)
• Map honey_bottle (with correct ID)

Entities:

• Map bees

Describe alternatives you've considered
Since Nukkit doesn't support blocks with high id and neither the new items, this remaps should be added:
Blocks:

• Erase bee_nest from the world (it's a natural block hanging on natural trees, an air replacement should be fine)
• Remap beehive to oak_planks (player made block, so a wall of it should still be a wall)
• Remap honey_block to slime_block (they are similar, not in color)
• Remap honeycomb_block to yellow_glazed_terracotta (they are similar in color)

Items:

• Preserve honeycomb as honeycomb (Nukkit doesn't support it officially, but can still display it if we use the right item id)
• Remap honey_bottle to mushroom_stew (the closest food in functionality)

Waiting this to continue PowerNukkit/PowerNukkit#99 . I'm going to make it create a NukkitX's compatible world format by default and an option to create a world using the GameModsBr's world format, which support all new blocks.

This will go in an other issue
