Details and comments

Some details that should be in this section include:

• Came from an issue that was open #1169 .
• What tests and documentation have been added/updated
• What do users and developers need to know about this change

What needed to do in this PR:

• [x] Add support for different subplot sizes.
• [x] Add automatic residual calculation.
• [x] Plot residuals.
• [x] Style the plot's color, legend, limits, etc.

When setting plot_residuals=True in analysis option, a residual plot will be added. currently work only for experiments with 1 plot in its figure. Example for output with plot_residuals=True for RamseyXY experiment:

Can the residual plot example be moved from the Ramsey manual to the Visualization tutorial? I think that's a place where users are more likely to lok for the information.
