zlib License

The licence of zlib, the general purpose compression library by Jean-loup
Gailly and Mark Adler. Bean Network Tester ships zlib1.dll as part of the
CPython Windows runtime; the exact version is reported by `--license` and named
in THIRD-PARTY-NOTICES.md.

Reproduced as the project publishes it at https://www.zlib.net/zlib_license.html
(retrieved 2026-08-11). The permission text is identical across zlib releases;
only the copyright year range moves, and the range below is the one carried by
the binary actually shipped here - `zlib1.dll` reports "deflate 1.3.1 Copyright
1995-2024 Jean-loup Gailly and Mark Adler" in its own strings.
