final appeal for generic on nostrevent

[antonioconselheiro]

I would like make a final appeal to include generic support to nostrify NostrEvent.

Continuation of: nbd-wtf/nostr-tools#448

If you know you don't want that you can say just no and ok,
but here are advantages by including this in your library:

1. default value as number make it retrocompatible to NostrEvent with no generic, no old software will feel the changes;
2. isKind() was just included to nostr-tools and as I demonstrated it makes the guard type cast except for switch case;
   
3. this pr Suggestion: export kinds as named types nbd-wtf/nostr-tools#447 also included use of kinds as a typescript type, so it's possible use like this: NostrEvent<ShortText>
4. while this code Suggestion: export kinds as named types nbd-wtf/nostr-tools#447 is not published in npm I'm doing this: NostrEvent & { kind: typeof kinds.ShortText }, a complex representation that will be common used to define kind validated events, nostrify can offer a simple symbol NostrEvent<ShortText>
5. NostrEvent is equal NostrEvent from nostr-tools but with docs, this will make it a best version for use to me.

So, no?
