Create Git tags and releases for versioning

[Emilien Macchi]

Hello DeepGEMM Maintainers,

First, thank you for your excellent work on this project! It's a very valuable tool.

I am writing to respectfully request that you consider creating versioned tags and releases for the repository.
Creating official releases with Git tags would make the project much easier for the community to consume, test, and build upon.

Please let me know if you need any guidance on Python packaging or release management; I work for Red Hat and we are willing to help if needed.

Thank you

[Emilien Macchi]

Sure, after a MoE backward kernel is merged, I will make a release. Thanks for your advice!
