Enhancements

• Adapters can now utilize a :delayed response from the Geolix.Adapter.load_database/1 callback combined with Geolix.Database.Loader.set_loaded/1 for a lazy initialization. The database will not be used for lookups until set to the :loaded state
• Database worker supervision is now done using a DynamicSupervisor
• Unloading a database can now be done by passing the complete database configuration instead of only the :id

Bug fixes

• Databases loaded without an adapter configuration can now be properly unloaded to prevent repeated error messages from Geolix.reload_databases/0
• The optional metadata/1 callback for adapters is now properly treated as optional

Backwards incompatible changes

• Internal adapter process pooling has been removed
• Minimum required Elixir version is now ~> 1.7
