Discussion on using "tidy evaluation" or not for column names

[lilyclements]

We generally do not use tidy evaluation but should have a discussion on this soon.

@dannyparsons in some functions, such as climatic_missing, we use the tidy evaluation method.

I'll list here functions we use tidy evaluation in, and so we can change either these functions later - or the functions not listed here to update to tidy evaluation.

In addition - we use rlang::quos on output_CDT (and perhaps other functions) taken from R-Instat. For consistency we should change these too to whichever system we go for?

[dannyparsons]

Maybe we should use one of these functions to demonstrate how the tidy evaluation could work? Seeing how it works with checkmate etc. to check its feasible. I don't mind having this inconsistency while we are deciding.

If it works well we can implement tidy evaluation throughout, otherwise we can change these to use strings.
