Subject: Add local event log storage (#390)

* Add event data structures

This adds the data structures required to start syncing events, rather
than syncing history directly.

Adjust event

Fix

Add event data structure to client

* Add server event table sql

* Add client event table migration

Adjust migration

* Insert into event table from client

* Add event merge function

Right now this just ensures we have the right amount of events given the
history we have

BUT it will also be used to merge CREATE/DELETE events, resulting in
history being deleted :)

* Make CI happy

* Adjust

* we don't limit history length any more

* Update atuin-client/src/database.rs

* fix usage

* Fix typo

* New Rust, new clippy stuff
