add nec demo

[rryoung98]

This pull request introduces a new Jupyter notebook demonstrating how to use the qBraid SDK to run a QUBO problem on the NEC backend. The notebook includes markdown explanations and code cells to guide users through the process.

Key additions:

• Introduction and Setup:

  • Added a markdown cell with an introduction to the qBraid SDK and its NEC integration. (qbraid_sdk/qbraid_runtime_nec.ipynb)
  • Included a code cell to install the necessary libraries using %pip install 'qbraid[runtime]' matplotlib pyqubo. (qbraid_sdk/qbraid_runtime_nec.ipynb)

• Code Execution:

  • Added code cells to import the QbraidProvider and initialize it. (qbraid_sdk/qbraid_runtime_nec.ipynb)
  • Added code cells to retrieve the NEC device status and profile. (qbraid_sdk/qbraid_runtime_nec.ipynb)
  • Included a code cell to run a QUBO problem on the NEC backend and print the results. (qbraid_sdk/qbraid_runtime_nec.ipynb)

I'm pretty sure pyqubo is already included as a dependency "extra", so you should be able to do

 %pip install 'qbraid[pyqubo]' matplotlib

also qbraid[runtime] is not a valid extra anymore as of v0.8.

And we were planning on changing the run_input from model to qubo right? To avoid the redundancy related to the offset param? Probably would wanna solidify this before we publish any demo

@ryanhill1 gotcha, yes, I will make those changes. I just wanted to have a place for the demo that is being used at CRS4.
