www/py-binarycookies: new port had been added (+)

Apple's Safari web browser binary cookies format (de)serializer
written in Python.  Our modifications to the original sources
include the fix for "the year 2038 problem" on 32-bit systems,
Netscape traditional `cookies.txt' file format support, and use
of Pydantic V1 which does not pull in Rust unlike V2 which the
project needlessly assumes by default.
