    /**
    * @author Matter Labs
    * @notice This library is used to perform ultra-efficient calls using zkEVM-specific features.
    * @dev EVM calls always accept a memory slice as input and return a memory slice as output.
    * Therefore, even if the user has a ready-made calldata slice, they still need to copy it to memory
    * before calling. This is especially inefficient for large inputs (proxies, multi-calls, etc.).
    * In turn, zkEVM operates over a fat pointer, which is a set of (memory page, offset, start, length) in the memory/calldata/returndata.
    * This allows forwarding the calldata slice as is, without copying it to memory.
    * @dev Fat pointer is not just an integer, it is an extended data type supported on the VM level.
    * zkEVM creates the wellformed fat pointers for all the calldata/returndata regions, later
    * the contract may manipulate the already created fat pointers to forward a slice of the data, but not
    * to create new fat pointers!
    * @dev The allowed operation on fat pointers are:
    * 1. `ptr.add` - Transforms `ptr.offset` into `ptr.offset + u32(_value)`. If overflow happens then it panics.
    * 2. `ptr.sub` - Transforms `ptr.offset` into `ptr.offset - u32(_value)`. If underflow happens then it panics.
    * 3. `ptr.pack` - Do the concatenation between the lowest 128 bits of the pointer itself and the highest 128 bits of `_value`. It is typically used
         to prepare the ABI for external calls.
    * 4. `ptr.shrink` - Transforms `ptr.length` into `ptr.length - u32(_shrink)`. If underflow happens then it panics.

    * presenting a message signed by the account. By not relying on {IERC20-approve}, the token holder account doesn't
    * need to send a transaction, and thus is not required to hold Ether at all.
