Method AddPayloadIntegrity

go/bundle/bundle.go:59–74

AddPayloadIntegrity encodes the exchange's payload with Merkle Integrity content encoding, and adds `Content-Encoding` and `Digest` response headers. It returns an identifier for the "payload-integrity-header" field of the "resource-integrity" structure. [1] [1] https://wpack-wg.github.io/bundled-r
