Aurora Proxy Factory

The main purpose of the contract is to provide the ability to deploy proxy token contracts for NEP-141 tokens. The purpose of the proxy token is to solve the issue of base tokens having a number of decimals that is not equal to 18. The problem exists because the MetaMask can only work with base tokens that have a number of decimals equal to 18. In another way, the balance in base tokens was displayed incorrectly in the MetaMask.
