ImageRequestOptions resolution setting enhancement

[cccif]

Describe the issue
The image saved with the following script will have the image "cramped" and legend is cut off.
"image_req_option = TSC.ImageRequestOptions(imageresolution=TSC.ImageRequestOptions.Resolution.High, maxage=-1)"
It will be flexible if the width of the image can be configured according to user's need.

Implemented. ImageRequestOptions accepts viz_width and viz_height (must be set together).
