deps: update nostr-tools to 1.10.1

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.
