This pre-commit is really hard...
I created #126 to fix the old name of plot_ctd.

After it is merged, I will continue trying to add plot_ts.
@ocefpaf, is there another name you think would better suit this function?

Ignore it until the PR is done. Then we can fix the pre-commits. It helps old developers like myself to handle projects when many contributors but it sure increases barrier for contributions.

After it is merged, I will continue trying to add plot_ts.

I merged #126 and rebased this one. You will need to perform a git pull on this PR branch locally to get the latest merged commit. Let me know if you need help with that.

I believe that plot_ts is fine. Let me know when this one is ready for review!

Maybe we should do the TS for the whole track. TS diagrams have many uses and the very first one is tp assess data quality, find oddities, etc. I believe that this function will be used to for quick data inspection like that, not really a final figure for a paper or refined research.

@ocefpaf , to create a plot with all the profiles, I would need to interpolate them so that they are in the same pressure intervals, adding NaN where the profiles are shallower than others. Do my thoughts make sense, or is there a simpler way?

I rebased it and remove the extra baseline directory inside the module. We keep the tests outside of it b/c we don't want to ship these PNGs with the package.
