Binary neighbourliness based on a simple rule where if a block has the same binary value as its 3 neighbours they become friends.

How this works under the hood:

1. Hash determines grid size
2. Hash is also converted into an array of numbers from chunking the hashes.
3. Hash is converted to binary and a subset of the binary string is chosen according to a hashed numeric value based on the grid size
4. If a block has the same binary value as its 3 neighbours they all take on the same properties and turn red.
