Create a new NFT collection for Holders with accumulative rarity

To encourage locked staking and generate liquidity for Pancakeswap, I suggest creating an NFT collection for holders with accumulative rarity.

At the end of 52 weeks, users with more than 100 cakes can choose to drop a simple NFT or keep locked for another 52 weeks and drop NFT with more rarity, this rarity can accumulate for up to 3 rounds of 52 weeks.

like squad collection, the holders of these NFT's have some advantages that can be decided by the chefs.
