Feat: SNARK proof verification

[julio4]

Description

Thanks to the amazing work of garaga it is now possible to verify SNARK proofs on Starknet. We want to show a use case of this with an example of a contract that rely on a deployed verifier to verify one proof and do something with the result.

An opening idea would be age verification where users can prove they are above a certain age without revealing their birth date.

Criteria:

• You can use any predeployed verifier contracts such as risc0, or deploy your own verifier (groth16, noir) (no need to explain how to deploy the verifier)
• Include an example of verifying a proof on testnet
• Have a working example that leverage private inputs for privacy and potential public inputs
