Minimal Upgrade Beacon Proxy (runtime code)

• Get the current implementation contract address from the upgrade beacon via STATICCALL
• Then, put calldata in memory to supply as argument in DELEGATECALL to implementation
• Finally, return or revert based on DELEGATECALL status, supplying return buffer in either case
• 48 bytes long when using an upgrade beacon with a compact address (starts with 5 zero bytes)

* @title Metamorphic Contract
* @author 0age, derived from cloner contract by @mhswende
* @notice This contract will create a metamorphic contract, or an upgradeable
* contract that does not rely on a transparent proxy, when deployed using
* CREATE2. It expects the deployer to provide a getImplementation() function
* that will return an implementation address, which it will then clone and
* deploy. Unlike with upgradeable transparent proxies, the state of a
* metamorphic contract will be wiped clean with each upgrade. With great power
* comes great responsibility - implement appropriate controls and educate the
* users of your contract if it will be interacted with!
