Add a ping interval setting that allows you to customize the websocket
ping interval. The default of 5 minutes may be too high for some proxy
servers that disconnect connections that are held open for too long.
This enables support for using the proxied IP from cloudflare. The damus
relay is behind cloudflare, so to get accurate remote ip logging we need
to look at the headers instead of the socket address.

These are pretty spammy on busy relays. I've been using the info log to
monitor spam attacks, and these are the least useful info log.
Leave the "stopping connection" log because it at least provides useful
sent/received information.

Implements core NIP-26 delegated event functionality. Events can
include a `delegation` tag that provides a signature and restrictions
on which events can be delegated.
Notable points on the implementation so far:
* Schema has been upgraded to include an index and new column.
* Basic rune parsing/evaluation to implement the example event in the
NIP, but no more.
* No special logic for deletion.
* No migration logic for determining delegated authors for
already-stored events.
Schema upgrades were buggy from 4->5 (the v5 would be skipped). This
change also refactors the logic slightly so that future additions can
be clearer (no need to have if and else-if combinations).
NIP-01 prefix search, and NIP-12 generic tags are no longer marked as
experimental.
NIP-11 relay info advertises NIP-09 event deletion and NIP-12 generic
tag search support.
The `reject_future_limits` option can now be disabled, and is by
default.
NIP-11 advertises support for created_at limits.
The message for future-dated events has been modified, to be closer to
the recommended example in the NIP.
Only lowercase and even-length tag values are stored as binary BLOBs.
Previously there was an error which search results from being returned
if the tag value was mixed-case and could be interpreted as hex.
A new database migration has been created to repair the `tag` table
for existing relays.

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.
This was quickly sneaked in by fiatjaf per my request[0], it makes many
queries more efficient and allows for paging when combined with until.
It is a bit weird to have multiple limits on each filter... for now we
just choose any or the last limit seen.
