[yt-dlp]Investigation for logger output to log file

As Youtube-DL was not extended any more, I turned to yt-dlp also.

But it has an insufficient feature to output debug log to stdout. In my program, I need it to output debug log to log file instead of output to stdout.

After take some time to investigate the source, I found that I need to change one method in below file.

yt-dlp/yt_dlp/utils/_utils.py
Method: write_string

Its source below:

def write_string(s, out=None, encoding=None):
    assert isinstance(s, str)
    out = out or sys.stderr
    if not out:
        return

    if compat_os_name == 'nt' and supports_terminal_sequences(out):
        s = re.sub(r'([\r\n]+)', r' \1', s)

    enc, buffer = None, out
    if 'b' in (getattr(out, 'mode', None) or ''):
        enc = encoding or preferredencoding()
    elif hasattr(out, 'buffer'):
        buffer = out.buffer
        enc = encoding or getattr(out, 'encoding', None) or preferredencoding()

    buffer.write(s.encode(enc, 'ignore') if enc else s)
    out.flush()

As per the source, we can add out put log file parameter to it.
