Withdraw tokens from ERC20 Bridge contract

This command is used to impersonate validators in the eyes of the ERC20 Bridge contract, so it allows withdrawing funds. This command ends up being handy when a network has crashed or is being reset but people didn't have time to withdraw their funds.

This requires private keys for all validators, and is meant for testnet ONLY.

Help

make build
./build/vegatools unsafe_withdraw_impersonate_validators --help

Running

Create the file validator-privkeys.json:

[
