Creat the time series data for the magnetic field

[ChiZhang123456]

Dear Louis,

This code is impressive! I've been using irf-matlab for MAVEN data analysis and am now transitioning to Python with pyrfu. I've constructed time series data using pyrf.ts_vec_xyz(time, Bxyz). Could you advise on how to add metadata such as coordinates (MSO), resolution (32Hz), and instrument (MAVEN MAG) to this data structure?

Additionally, I've encountered some issues with the "pycdfpp" while following the tutorial on CDF. It sometimes fails to work. Is "spacepy.pycdf" a more reliable alternative?

Thank you
Best Regards
Chi Zhang
