privacy provisioning for star funding the urbit ecosystem

1. prove a galaxy point as a zk proof in c $ ./galaxy/ownership
2. spawn stars off-chain in c by proving with zkp a range of values and if valid select with a random number (where a random number oracle can be replaced) $ ./star/range_proof
3. generate a proof for the spawning of that star to redeem for erc20 tokens onchain $ ts-node ./optionality/evm/ERC20/ts/generate_signature.ts -> ./optionality/evm/ERC20/sol/ERC20.sol
4. redeem star by off-chain writing to chain in step 2) from central funder, then on-chain proving ? -> ./ERC721/sol/MockAzimuthWrapper.sol
