Method SetTLSFingerprint

client.go:1227–1230

SetTLSFingerprint set the tls fingerprint for tls handshake, will use utls (https://github.com/refraction-networking/utls) to perform the tls handshake, which uses the specified clientHelloID to simulate the tls fingerprint. Note this is valid for HTTP1 and HTTP2, not HTTP3.
