14. User generates sign up proof

npx ts-node cli/index.ts genUserSignUpProof \
    -x $UNIREP_CONTRACT_ADDRESS  \
    -id $USER_IDENTITY  \
    -a $ATTESTER_ID

NOTE: -a is attester's id. If the attester gives the attestation with a sign up flag, the user can generate a sign up proof to prove the membership from the attester.

See: cli/genUserSignUpProof for more genUserSignUpProof options.

The proof will be printed and it should be handed to the receiver of this proof, for example,
