add fromString method alternative

I’d like to migrate from uuidv4, as suggested in that repo. I’m using the function fromString which doesn’t exist in this repo. I see the uuid.v4() function accepts several options, but I don’t see a way to create a uuid given a string. Could you provide this functionality or document it if already available?

@correttojs The deprecation message warning provided by uuidv4 tells you (mostly) how to do this - use the v5() method. E.g.

import {v5 as uuidv5} from 'uuid';

uuidv5('string to create uuid from', 'bb5d0ffa-9a4c-4d7c-8fc2-0a7d2220ba45');

(@ctavan: uuidv4’s fromString() method is a wrapper around v5 namespace uuid creation. See source.)

The one fiddly bit is the custom namespace (“bb5d0ffa-…”) you need to provide if you care about backward compatibility with previously generated fromString() ids. Otherwise you can use uuidv5.DNS or uuidv5.URL instead, or create your own namespace id as described in our docs.

Cc: @goloroden for possible improvements to deprecation / migration instructions in uuidv4 codebase.

Closing in favor of https://github.com/thenativeweb/uuidv4/issues/219 since there’s nothing actionable on our end.
