Added capacity to calculate trends from observational datasets for plotting in Roach-style plot only (as Notz-style includes a "plausible" range that is beyond scope).

Observations are shown as squares.

Annual trend in siconc for NOAA dataset is slightly different between this and Roach's figures, 0.01677... vs 0.01692....

Annual trends for GMST were taken as one average in Roach's plots, so will not be identical.

Direct sensitivities (such as plotted in the Notz-style plot) are calculated for each observational pair [as the calculation was already running to produce correlation coefficients], but are not shown in any plots (they are saved in the csv files though).

Checklist

It is the responsibility of the author to make sure the pull request is ready to review. The icons indicate whether the item will be subject to the 🛠 Technical or 🧪 Scientific review.

New or updated recipe/diagnostic

New or updated data reformatting script


To help with the number of pull requests:

 - Removed obs from Roach-style graphic (left description for reference).
 - Fed in model datasets from recipe differently to allow for obs having a different variable.

 To do:
  - Calculate and plot the obs.
  - Print the obs trend values.

please give the PR a suitable title, when you have a minute (even if it's a draft) 😁

I don't know what this is, but running the recipe seemed to fail unless I removed it...
