Support Nil and Max UUID formats from RFC 9562

[ngnpope]

Feature or enhancement

Proposal:

RFC 9562 defines Nil and Max UUID formats:

• https://www.rfc-editor.org/rfc/rfc9562.html#name-nil-uuid
• https://www.rfc-editor.org/rfc/rfc9562.html#name-max-uuid

I've often had a need to use these as placeholders, sentinels or dummy values and it would be nice to be able to write uuid.NIL and uuid.MAX instead of uuid.UUID(int=0) and uuid.UUID(int=2 ** 128 - 1) every time I need to reach for them.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

Thanks for this one. I planned to add it at some point but it's good that someone else did it as it's an easy feature to add.
