Request to Lower Python Version Requirement to 3.12

[vladkolotvin]

Dear @porimol,

Thank you for your work on the CountryInfo library! It is an excellent tool that I frequently use in my projects.

I noticed that the latest release requires Python 3.13 as a minimum version. However, Python 3.13 has been released very recently, and many other libraries and environments have not yet added support for it. This creates difficulties for users who rely on compatibility with a broader ecosystem.

Considering that there may not be critical features in the library that specifically require Python 3.13, would it be possible to lower the requirement to Python 3.12? This would make it easier for developers to adopt the new version of your library without disrupting their existing setups.

Thank you for your consideration, and I appreciate your efforts in maintaining and improving CountryInfo!

Best regards,
Vladislav
