Add interval option for Guider reply

[iipeace]

Using 1 second as default interval may cause data loss,
So could you add interval option for Visualizer?
And I guess it would be best to apply 3 second as default interval.

@iipeace
Can you implement the interval setting function in the guider API? ex) GUIDER reptop -Q -3
With that feature, it seems possible to implement a user input from the visualizer.

-i option for interval already exists :)

@iipeace
How can I call? Documentation for the guider server API could not be found in README.

GUIDER reptop -Q -i 3

could you try the command?

Okay! :)
