* create a new type for crypto stream used for Initial data This currently the exact same implementation as the other streams, thus no functional change is expected. * handshake: implement a function to find the SNI and the ECH extension * move the SNI parsing logic to the quic package * implement splitting logic * generalize cutting logic * introduce QUIC_GO_DISABLE_CLIENTHELLO_SCRAMBLING * improve testing
