Please hold off on this until the license controversy is resolved.

RE: [OE-core] [PATCH] python3-chardet: upgrade 5.2.0 -> 7.0.1

[Song, Jiaying (CN)]

Hi Zoltán,

Thanks for the feedback. You're right - I'll hold off on the 7.x upgrade due to the ongoing license controversy.

Background:
The 7.0.0+ versions were rewritten by maintainer Dan Blanchard using Claude AI. He claims it's an independent work not derived from GPL/LGPL code, justifying the MIT license change. 
However, the original author Mark Pilgrim objected on March 5th (https://github.com/chardet/chardet/issues/327), arguing that AI-assisted rewrites still reference the original LGPL code and should remain under LGPL.

Current Status:
Based on Dan Blanchard's final comment (https://github.com/chardet/chardet/issues/327#issuecomment-4017410801), this license dispute is unlikely to be
resolved soon. He locked the discussion without changing his position.

Solution:
I've submitted a new patch upgrading to 6.0.0.post1 instead - the latest version without license controversy. This maintains LGPL-2.1-only and avoids
potential compliance risks.

Thanks,
Jiaying.
