#' 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 two files are provided, the function will treat them as data for each gender, returning a combined dataset. If only one file is provided, the function will assume that it represents data for a single gender.

file1: Name of the first file containing data downloaded from the K-T database.
file2: Name of the second file containing data downloaded from the K-T database.

male_first: Indicator of whether file1 is for males. Default is TRUE.
