// Class TrustTokenRequestIssuanceHelper handles a single trust token issuance
// operation (https://github.com/wicg/trust-token-api): it generates blinded,
// unsigned tokens using an underlying cryptographic library, asks a token
// issuer to sign the tokens, verifies the result, and unblinds and stores the
// tokens. The normal case involves a total of two network requests: one to get
// an up-to-date view of a key set the issuer provides for verifying its
// signatures, and another to send blinded tokens to the issuer.
