Bump to v5

Release text

The signature of read_password_with_reader has changed from:

pub fn read_password_with_reader<T>(source: Option<T>) -> ::std::io::Result<String>
    where
        T: ::std::io::BufRead

to

pub fn read_password_with_reader<T>(source: Option<&mut T>) -> ::std::io::Result<String>
    where
        T: ::std::io::BufRead

This allows to call read_password_with_reader multiple times with the same reader. Thanks @dvermd for this contribution!
