Build lines with fixed IPs:
  hybrid-pin.sh [-t socks5|http] HOST:PORT:LOGIN:PASSWORD [HOW_MANY]

Verify saved lines:
  hybrid-pin.sh verify [-t socks5|http] [FILE]

HOW_MANY defaults to 10, the result goes to pinned.txt.
A socks5:// or http:// prefix on the line overrides -t. With neither, SOCKS5 is used.
