feat: add p/uuid

[DIGIX666]

I suggest adding a UUID package because I think it could be useful to have it available. I think it can further facilitate traceability and compatibility between different systems and apps as they would have a common standard for identifying entities.

To improve UUID generation, I wanted to add a resolver like Snowflake, but from what I've searched, sync/atomic is not supported on Gno. Is there another similar package that I might have missed ?

There is no other way to guarantee atomicity besides using time in environments where atomic is not supported. If we consider it further, it seems possible to generate a random value (using crypto/rand or not merged yet, but maybe later) like a machine ID, assign it, and then combine it. Of course, this is slightly different from the implementation of Snowflake.

It seeme like LastSequence does not used.

Indeed, I had forgotten to remove it after my tests for the resolver. Thanks

It would be nice to leave the comments in English

Thanks for your explanation. I will check the progress of crypto/rand to try to use it.
