Kujira Crank

This crank app uses a single "orchestrator" account, and sets up feegrants to allow concurrent cranking of the BOW Contracts and USK Liqudiations.

Long-term this will be replaced by the on-chain scheduler. Until then, this app allows us to understand the dynamics of these crankers before committing to the scheduler.

## Setup

1. Ensure that you have MNEMONIC available on your env for the orchestrator account
2. yarn
3. NETWORK=mainnet yarn start

NB: On first start, all the feegrants will be created which can take some time
