Helper method to merge claim topic, claim, and attempt decryption/verification

I've added a NeoVivid class to the sdk which includes a high-level method to getting and decrypt claims using the smart contracts. Usecase notes:

If an attestation has decrypted_value === undefined, the user was unable to decrypt the attestation payload. This can happen for a number of reasons. In the case of our UI, decrypted_value === undefined display *********** for the value

example:



const claim = await sdk.Vivid.getDecryptedClaimByClaimID(this.neo_network, this.contracts.neo_cns, claim_id, this.contract_admin_wif)

console.log(claim) 
/*
{ claim_id: 'GBwRsliN49Bs7bPW',
  attestations:
   [ { remark: '',
       value:
        '6895edfb152af6e66e1a6f7e90b435976a1c312c7ccf96e0d2695b25cafd8163',
       encryption: 'symmetric_aes256',
       identifier: 'EMAIL',
       decrypted_value: 'clementine84@gmail.com' } ],
  signed_by:
