feed: subscribe to pow events

if difficulty-filter is set the subscription of the global feed can filter only ids with 0-prefix to save bandwidth. as there may not be many pow events within the last 24h, the date range is now only enabled if there is no diffculty-filter set so that the feed is not empty. if this works as expected it could also only subscripe to reactions and profile info with pow ids. deps: update nostr-tools to 1.10.1 This version supports subscribing to prefixed ids, see 3bdb68020d
