When an SSH channel is used for a file transfer, the summary will report
the detected direction of the file transfer as either an upload or
download, relative to the end client.
This was originally introduced to ensure that the meta files only
included ascii characters. However, this makes reading the protocol from
meta file less reliable since it does not exactly match the protocol
string. Instead protocol strings will be recorded in the meta files as
is. Generally protocol strings should include readable characters.
This also updates the ssh.Protocol to be 4 readable characters.
This adds a function for decoding all of the SSH Chunk types and
registers the function with the chunk types so that the bsr.ChunkDecode
can be used to decode SSH Chunks.
