'transform_subset_age()' subsets the rows in a LIS/LWS file so all cases have
ages between two values (both included), returning a list with the files
containing only rows where the age is between those values. I.e. a subset
of rows.
It can also be called with 'transform_filter_age()'.

An integer with the lower boundary value (included in the sample).
