title: File import callback not supported?
body: <p>Tried to run:</p>
  <p>1.) Dappuniversity project (dappuniversity/dbank)
  2.) pet-shop-tutorial</p>
  <p>Truffle v5.3.3 (core: 5.3.3)
  Node v14.15.5</p>
  <p>How can ser compile code @ the 0.8.4 to import OpenZeppelin’s ERC20.sol template, when Truffle requires it’s compiler/solc to match 5.3.3?</p>
