Upgrade nostr-tools to v1.7.4

[alexgleason]

The latest nostr-tools includes important fixes for Deno which also affects this package.

I had to revert it because it breaks the tests. At the same time of course we should upgrade nostr-tools

[adamritter]

Merged again with ignoring type arrors about sig missing (which can be optionally deleted)

[adamritter]

Also I released nostr-relaypool 0.5.14 with the change
