Remove options --response-wait, --response-timeout

Remove options and rework input handling so it is possible to do the
same thing but via script which is much more flexible.

These options were always a bit of a hardcoded solution. With the new
script expect feature we can wait for any type of response.

For example, pipe command to serial device and wait for line response within 1 second:

$ echo "*IDN?" | tio /dev/ttyACM0 --script "expect('\r\n', 1000)" --mute
