Settings for checking outdated data when authorizing via telegram.

[Graphanton]

Added the ability to set the period for checking outdated data when authorizing via telegram.

If the time of the telegram server differs from the time of your server...

Wouldn't it be better in this case to actually fix the root cause and make sure your server is running NTP so that the time is not out of sync?

[Graphanton]

Yes. I removed it myself. But since Telegram does not strictly regulate the authorization expiration time, I can set my own expiration time, which can be less than the default.

coverage: 91.328% (-0.2%) from 91.489% when pulling 5a03539 on Graphanton:main into bd61beb on pennersr:main.

I am okay with adding this functionality, though I think it would be good to reword the documentation. Because "If the time of the telegram server differs from the time of your server..." you need NTP and not this change.

Thanks for rewording. One last thing, the code is not black formatted causing the build to fail. Can you look into that?

Ready!
