Move UUID from C to Go

[ncruces]

Be as compatible with uuid.c as possible. But support new UUID formats.

Hi @ncruces. New here to OSS. I'd like to take this up and make my first contribution.

That's great!

I'm looking for these 3 functions (more docs here):

uuid()        - generate a version 4 UUID as a string
uuid_str(X)   - convert a UUID X into a well-formed UUID string
uuid_blob(X)  - convert a UUID X into a 16-byte blob

For parsing I'm fine with just using Parse (no need to be exactly 100% compatible with the C version).

Then I'd like to (somehow) overload the uuid() to generate other kinds of UUIDs. Particularly V7, maybe just uuid(7). But other kinds would be good.

These should be helpful to get you started:

• the Unicode package
• the CreateFunction example

Thanks!!
But I've never contributed to Open source and this repo doesn't have any guidelines about How to contribute that I could see.
Could you maybe provide a hint in the right direction?
That'll be super helpful

Well, I'm not sure I can help much with that part except point to docs:
https://docs.github.com/en/get-started/exploring-projects-on-github/contributing-to-a-project

[suyash-sneo]

Sure, I'll refer to that. The material you have shared should help me get started so thanks for the help :)

Removing the current uuid function and making it an extension is a minor breaking change.

I'd like to bundle it with #111 (another minor breaking change) before the next release.
