Document post-deprecation support timeframe

[NateEag]

The readme clearly states that this package is deprecated and people should use cuid2 instead.

It's not clear whether this package is still supported.

Is the package still supported?

If it is, is there a defined time after which support will end?

This package has been done and API stable for years, and will likely continue to work fine for many more years. In the unlikely case that it requires maintenance updates, I would push new versions. However, there are no plans to add features or update the API in any way, and for security, I strongly recommend switching to an opaque, non-timestamped, non-monotonic id generator like Cuid2.

That all makes sense. Thanks for clarifying!
