Actor.sol:120: Use of delegatecall is not allowed

[ttsszzyy]

Error: Contract contracts/Miner.sol:Miner is not upgrade safe

@zondax/filecoin-solidity/contracts/v0.8/utils/Actor.sol:120: Use of delegatecall is not allowed https://zpl.in/upgrades/error-002

使用hardhat做可升级部署时，出现了这个错误。升级方案用的是uups模式。

FEVM only allow delegatecall to call actor.

This can be solved in Solidity like Alex Wade solved it here: https://github.com/wadealexc/fevmate/blob/main/contracts/utils/CallNative.sol#L53-L63

This basically "hides" the delegatecall from the compiler; it's not the best solution but it works today.
