doesn't seem to pass a last two tests:
Rejects submission of event before address is deleted: UNTESTED (blocked: not replacing newer parameterized replaceable event)
Accepts submission of event after address is deleted: FAIL (blocked: not replacing newer parameterized replaceable event)
but this may be because it tombstones deleted events and is rejecting resubmission of an older version that was thus deleted, so i'm calling it done
add flatten flag for store so it flattens on request at shutdown if an import has taken place
import runs GC every 10000 events to limit fragmentation of tables
implement a specific count function that only decodes the event if there is an extra filter (which should be the minority of cases)
change search to use maps for indexes to automatically deduplicate in case of multiple queries matching the same field
improve logging to show origins of request/events in relay accept req/event
count now returns an aproximate flag for the case of extrafilters finding replaceable events
