still encountering problems when trying to submit a multisend tx. they are mostly coming from gas estimation:

• prepare_transaction tries to estimate gas from a safe address
  • it fails when the safe has no ether to cover the gas costs, but in reality safe itself never pays for gas
  • it fails because it tries to estimate a call to the multisend contract, while it only supports delegatecall

we need to somehow override the tx handler or find a way to pass additional metadata to skip some checks

@banteg for this PR, @dtdang is gonna focus on making sure it works against the Goerli SafeAPI and finish up by documenting as much of the new functionality as possible, so we can get this merged and move on to the other bug fixes needed

type checking will fail until ApeWorX/ape#1793 is released
