#' Read old-age mortality data from files downloaded from K-T database

read_ktdb_file reads old-age mortality data from a file downloaded from K-T database (https://www.demogr.mpg.de/cgi-bin/databases/ktdb/datamap.plx) and constructs a vital object suitable for use in other functions.

If only one file is provided, the function will assume that it represents data for a single gender.

Arguments
