Adapt the code in thyroid-cancer-prediction

[ns-rse]

The ns-rse/evaluate-modelling:docs/modelling*.qmd repository/branch has example workflows setup for a range of
"machine learning" statistical classification models. The results can be seen on the webpage
here along with greater details explaining the
concepts of splitting the data into training/testing, cross-validation some light overview of the methods being used and
explanations of how the predictive accuracy can be assessed.

These use a simulated data set but the workflow is adaptable to the Sheffield data now it is available.

The code needs copying over to this repository and working into the index.qmd so that the modelling runs and summaries
of the models are made in the manuscript.
