TLS Fingerprint generation fixes in MTProtoKit ClientHello

[zarv1k]

Hi! Is there any change to merge and release the new version soon with the ClientHello fix as on iOS Telegram client?

TelegramMessenger/Telegram-iOS#2089

This solves the problem of using MTProto under censorship conditions.

Thank you

Not a Telegram dev, just a regular user, but I would like to add my experience with the Telegram censorship so far.

I have version 12.6.279905 AppStore and MTProto connection doesn't work in Russian networks. However yesterday we received version 12.6.2 on iOS with the fix mentioned in OP and it works perfectly.

Also Telegram Desktop has this fixed already (telegramdesktop/tdesktop#30513) so we definitely need the fix for macOS as well

Android 12.6.4 - ok
macOS Telegram Desktop 6.7.6 - ok
macOS TelegramSwift 12.5.279893 beta - fail
macOS TelegramSwift 12.6.279903 Stable - fail

TelegramSwift is the worst.

Guys, can you merge the fix ASAP please? Swift version of Telegram is only version that unusable now because of this.
