234a8ba0ac feat: limit event publishing to NIP-05 verified users 
This adds a new configurable feature to restrict event publishing to
only users with NIP-05 verified metadata.  Domains can be whitelisted
or blacklisted.  Verification expiration and schedules are
configurable.

This upgrades the database to add a table for tracking verification
records.

4cc313fa2d fix: cleanup database connections with same name 
When a large number of subscriptions is created with identical names,
we do not send a signal over the abandon-read channel.  This

af453548ee feat: allow author and event id prefix search

filter to include a prefix for authors and events.

2d28a95ff7 feat: allow arbitrary tag queries 
This is an experimental feature, outside of any NIP, that demonstrates
generic tag queries.

Instead of limiting subscription filters to just querying only "e" or
"p" tags (via `#e` or `#p` attributes), any tag can be queried.

As an example, consider an event which uses a tag "url".  With this
modification, a subscription filter could add a top-level field
"#url", with an array of strings as the key.  Exact matches would be
returned.

A NIP is forthcoming to formalize this.

refactor: add strictly typed tags 
* Add custom error variant

This can be useful to propagate errors not conforming to available
variants. Also to convert other errors in `crate::Error` without having
explicit conversion defined, with `error.to_string()`

* Implement `Tag` and define protocol serialization

A Tag structure have been implemented with dedicated field types. Then
custom serde serialization is derived to map the structure to current
protocol json array as per NIP01.

This adds compile and run time type checking to always ensure wrong
string data are never stored or processed. With strict typed fields and
custom serde derivation this checks can be done at time of serialization,
saving work for internal handling of the actual data.

tests for possible data violations are added, and gives good example of
kind of errors it will through for different cases.

* Use String for URL

1589268eba fix: use database to publish all events 
This fixes a race condition where a publisher might send an event, and
immediately after issue a subscription for the same event ID.  Prior
to this change, that event would have been published on the broadcast
channel (and ignored by our publisher, because they had not yet issued
the subscription), but not yet committed to the database.  Their
subscription would trigger a database query which would return zero
results.  Therefore, they would never see the event they published.
The noscl tool is one client that would suffer from this.

Now, all events are broadcast only after they exist in the database,
so a late subscription will always return the event.
