Helper function to transform values in a data.table

1	transform_dt(dt, value_col, transformation, transformation_arguments)

`dt`	[`data.table(1)`] The data.table to apply the transformation functions to.
`value_col`	[`character(1)`] The column in `dt` to transform.
`transformation`	[`function(1)`] NULL if no transformation. Otherwise transformation function to apply to `value_col`.
`transformation_arguments`	[`list()`] NULL if no transformation. Otherwise list of arguments to provide to the corresponding `transformation` function(s).

invisibly return dt with transformed values.

popMethods:::transform_dt(
  dt = data.table::data.table(year = 1950, value = 2.5),
  value_col = "value",
  transformation = demUtils::logit,
  transformation_arguments = list(domain_lower = 0, domain_upper = 5)
