1c14adc766 fix(NIP-01): allow limits on a per-filter basis
The original implementation of subscription limit applied to the
entire query, instead of the specific filter.  Now, each filter gets
its own query limit.  When a limit is applied, the most recent N
events will be returned, otherwise the default is to return the
earliest events (in order), for all matching events.
