Pass connection and read timeouts to image data socket.

[sjamesr]

SANE uses separate connections for control and image data. Currently, the control socket uses connection and read timeouts that can be specified by the user in the SaneSession.withRemoteSane methods. The image data socket uses no timeouts whatsoever. This can cause infinite delays in the case of network issues.

This change passes the user-specified connection and read timeouts to the data socket.
