A realistic way of funding an attacker's account when testing

To avoid discovering false-positives, and promote the use of "good practices" within the web3 whitehat community, we are adding to **Forge POC Templates** the `dealFrom( token, from, to, amount )` cheat-code, which impersonates the user `from` using the `prank` cheat-code and does a normal transfer with `token.transfer(to, amount)`.

The implementation is very simple:
```solidity
   /**
     * @notice transfers tokens from one address to another using a Prank call.
     * @param token The address of the ERC20 token to transfer.
     * @param from The address to transfer tokens from.
     * @param to The address to transfer tokens to.
     * @param amount The amount of tokens to transfer.
     */
    function dealFrom(
        address token,
        address from,
        address to,
        uint256 amount
    ) public {
        vm.prank(from);
        IERC20(token).transfer(to, amount);
    }
```

This is the most realistic way of funding an attacker's balance while testing a system or creating a proof of concept.
