Use Pink Extension

Introduction
All the unique capabilities of Phat Contract are implemented in pink-extension. Informally speaking:
Phat Contract=ink!+Pink ExtensionPhat\ Contract = ink! + Pink\ ExtensionPhat Contract=ink!+Pink Extension
It is worth noting that the Phat Contract is not a trivial extension of ink! contract since all these extra functions only work under the off-chain computation.
