By default, \phpseclib\Net\SCP::put() does not read from the local filesystem. $data is dumped directly into $remote_file.
So, for example, if you set $data to 'filename.ext' and then do \phpseclib\Net\SCP::get(), you will get a file, twelve bytes
long, containing 'filename.ext' as its contents.
Setting $mode to self::SOURCE_LOCAL_FILE will change the above behavior. With self::SOURCE_LOCAL_FILE, $remote_file will
contain as many bytes as filename.ext does on your local filesystem. If your filename.ext is 1MB then that is how
large $remote_file will be, as well.
Currently, only binary mode is supported. As such, if the line endings need to be adjusted, you will need to take
care of that, yourself.
