This uses a binary number of 4 digits to encode the info.

The encode is:

|

Bit: 1 2 3 4
|

Side: x y -x -y
|

Values: bit = 0 -> The corresponding side block is not blockid
|

bit = 1 -> The corresponding side block is not blockid
|

Example: if the bit1 is 1 that means that there is a block with
|

blockid in the side of the +x direction.
