add pink slimeblock for storage purpose

[AiDSl]

for storage purpose,it can just be lazy colored slime block.
but if we really need to give it special property,I will choose that it dont even stick to other pink slime block.
(so row of pink slime block will work like alternating color slimeblock,all work indepandantly never form a structure)
(still can stick to regular block,but it is limited to directly connected block)
