Feature: Enhanced SUNA Data Processing and Quality Control

[JiaxuZ]

This pull request introduces several key enhancements and updates to the SUNA data processing pipeline within the EcoFOCIpy package. Major improvements include temperature and pressure corrections, advanced quality control based on RMSE, and integration of shipboard nitrate measurements for absolute value correction.

Summary of Source Code Changes:

• Temperature and Pressure Corrections: Implemented temperature and pressure correction algorithms for SUNA measurements.
• Quality Control Enhancement: Introduced multi-level QC based on the newly generated RMSE.
• Calibration with Shipboard Nitrate Measurements: Added functionality to adjust absolute values using shipboard nitrate data, with step-by-step instructions for manual QC integration.

Additional Changes in the Jupyter Notebook Example:

• Nearest CTD Cast Selection: Optimized the process for finding and using the nearest CTD cast data based on horizontal distance and depth matching.
• Improved Plotting Functions: Modularized and enhanced plotting functions for better visualization of SUNA data across various correction and QC stages.
• Documentation Updates: Added and polished documentation, including examples for using user-provided calibration files and interpreting results from multi-level QC.

Notes:

• This PR includes merging the latest updates from main into feature/suna to ensure compatibility and consistency with recent changes in the primary branch.
• Additional testing was conducted to confirm the accuracy of the corrections and the robustness of the QC pipeline.

Future Work:

• Further development for data output following the EcoFOCI data formatting.
• Integration of additional calibration files.

Please review the changes and provide feedback.

I think this looks great @JiaxuZ and I will accept it as is. Some very simple code-checks are failing (like import order of libraries) but these will be easy to clean on my end as I have some other similar tasks to do to the codebase
