Nv pulse shape change

Explanation of changes

I have made the following changes:

• Renamed the SpectroscopyOperationHermiteMW to SpectroscopyOperationNV.
• changed the nv_pulse_spec_mw in the pulsefactory to perform the sqaure pulse by default but could also perform hermite and gauss.
• changed the Rxyhermite to RxyNV
• changed the rxy_hermite_pulse to rxy_pulse that can perform hermite or gauss

Motivation of changes

As far as I have done the literature survey for the NV centers, majority of them use square pulse shape instead of hermite. But I do not want to take away that option, that is why I provided a choice in nv_pulse_spec_mw.

Merge checklist

See also merge request guidelines

• Merge request has been reviewed (in-depth by a knowledgeable contributor), and is approved by a project maintainer.
• New code is covered by unit tests (or N/A).
• New code is documented and docstrings use numpydoc format (or N/A).
• New functionality: considered making private instead of extending public API (or N/A).
• Public API changed: added @deprecated and entry in deprecated code suggestions (or N/A).
• Newly added/adjusted documentation and docstrings render properly (or N/A).
• Pipeline fix or dependency update: post in #software-for-developers channel to merge main back in or update local packages (or N/A).
• Tested on hardware (or N/A).
• CHANGELOG.md for breaking changes and AUTHORS.md have been updated (or N/A).
• Update Hardware backends documentation if backend interface change or N/A
• Check whether performance is significantly affected by looking at the Performance metrics results.
• Windows tests in CI pipeline pass (manually triggered by maintainers before merging).
  • Maintainers do not hit Auto-merge, we need to actively check as manual tests do not block pipeline

Summary by CodeRabbit

• New Features

  • Enhanced flexibility in spectroscopy operations with the ability to specify pulse shapes ('Square' or 'Hermite').
  • Introduced a new method for selecting pulse shapes based on user input.

• Improvements

  • Updated class and method names to better reflect their functionality and purpose.
