When called within a consistency test mapper function,
check_mapper_input_colnames() makes sure that the input data frame has
correct column names:
They include all the key columns corresponding to the test applied by the mapper.
They don't already include "consistency".
If either check fails, the function throws an informative error.
check_mapper_input_colnames(data, reported, name_test)No return value. Might throw an error.
Data frame. Input to the mapper function.
String vector of the "key" column names that data must
have, such as c("x", "n") for grim_map().
String (length 1). Short, plain-text name of the consistency
test that the mapper function applies, such as "GRIM".

columns" terminology.
