gnosis safe implementation

brownie-safe has call traces in their preview methods, which i think is out of scope in this particular case.

Also, there are implementations to sign with trezor or frame or ledger etc. whereas i think we should simply stick to browsersigner in this case. let users use notebooks to sign transactions, post them, fetch status on pending transactions, execute transactions etc.

The other issue I see with this is: if we integrate safe into boa, we would need to import web3py and that's going to bloat boa.

i don't see why that would be the case. besides, it should probably be a separate package anyways.

The api I recommend is:

with boa.safe.build_transaction():
    coin.approve(safe, 2**256-1)
    safe.spend(coin, 10**18)
    coin.approve(safe, 0)

is this issue ready?
