Esmerald

Changed

- ChildEsmerald now supports the parent which means it can share middlewares and interceptors
across main application and children.

!!! Note
Prior to version 0.16.0, sharing resources between Esmerald and ChildEsmerald was not allowed
and it needed to be treated as completely isolated application. In the version 0.16.0 you can
still isolate them but you can also share resources.

Added

- Esmerald [Pluggables](https://esmerald.dymmond.com/pluggables.md) [#60](https://github.com/dymmond/esmerald/pull/60).

This is the feature for the esmerald ecosystem that allows you to create plugins and extensions for any application
as well as distribute them as installable packages.

- New [add_child_esmerald](https://esmerald.dymmond.com/routing/router.md#add_child_esmerald) allowing adding via function, ChildEsmerald [61](https://github.com/dymmond/esmerald/pull/61).

Add child esmeralds via functions once the application is created and dynamically.

Added

- Brand new support for [Saffier](https://saffier.tarsild.io). A brand new ORM running
on the top of SQLAlchemy in an async fashion.
- New `base_user` and `middleware` support for Saffier with Esmerald.
- New docs regarding the [Saffier](https://esmerald.dymmond.com/databases/saffier/motivation/) integration.
Those include also an example how to use it.

Changed
