CopyRawConnIfExist use the most efficient copy method.

ReshapeMultiBuffer prepare multi buffer for padding structure (max 21 bytes).

XtlsFilterTls filter and recognize tls 1.3 and other info.

XtlsPadding add padding to eliminate length signature during tls handshake.

XtlsUnpadding remove padding and parse command.

TrafficState is used to track uplink and downlink of one connection It is used by XTLS to determine if switch to raw copy mode, It is used by Vision to calculate padding.

VisionReader is used to read xtls vision protocol Note Vision probably only make sense as the inner most layer of reader, since it need assess traffic state from origin proxy traffic.

VisionWriter is used to write xtls vision protocol Note Vision probably only make sense as the inner most layer of writer, since it need assess traffic state from origin proxy traffic.
