ERROR: MbedTLS.SSLContext does not support byte I/O

Can you support this? The ordinary socket could be read by readuntil and 'readline' funtions.

julia> readline(c)

My feeling is that supporting one-byte-at-a-time IO, and thereby allowing use of readuntil, readline, etc would encourage inefficient code because one-byte-at-a-time loop inside readuntil would call all the way down into the TLS library.
Better to use a buffering wrapper like https://github.com/BioJulia/BufferedStreams.jl

@samoconnor ,Thanks you, I used IOBuffer finally.
