Fix/2q rb

• Swap the order of the circuit_depth and repeat axes in both the QUA program and analysis, leading to more sensible results and reduced dependence on the circuit-depth density.
• Fixed the extraction of the fidelity by correcting the initial guess
• Improve the plotting of the decay curve by adding error bars at one-sigma
• Added feature to plot the state distribution as it evolves over circuit depth for debugging leakage.

It's a bit out of the scope, but we don't want examples under the "qualang_tools" folder, we have a separate example in the root of the git.
Can you move it there as part of this PR?
