Consider supporting deflate64 in zipfile

Feature or enhancement

Proposal:

Among the third-party projects that monkeypatch zipfile to support additional compression formats is https://github.com/brianhelba/zipfile-deflate64 with notes at https://en.wikipedia.org/wiki/Deflate#Deflate64,_Enhanced_Deflate about the "proprietary nature"

I wish adding additional formats didn't require monkeypatching, but in the meantime this is one of the ones that files containing it exist in the wild.

Has this already been discussed elsewhere?

まず、Python の zipfile 実装とリンク先の zipfile-deflate64 プロジェクトを確認し、次に monkeypatching を使わずに Deflate64 のサポートを組み込める方法を評価します。フォーマットのライセンスと独自仕様上の制約を確認し、zipfile を通じて Deflate64 圧縮を使用したファイルを開けることを完了条件とします。
