Saffier

Added

- Support for SQLAlchemy 2.

- `DatabaseClient` is now being directly used from [Databasez test client](https://databasez.tarsild.io/test-client/).

Fixed

- Updated requirements.

Changed

- Updated requirements to support Esmerald >= 1.1.0 for testing.
- Updated testing and docs requirements.

- Documentation regarding the reflection of tables. [37](https://github.com/tarsil/saffier/pull/37)

Added

- Integrated the support for [native migrations](https://saffier.tarsild.io/migrations.md) with Saffier.

* This brings native generated migrations within Saffier under Alembic's package, allowing
a seemless integration and cross-compatibility with any framework using Saffier.

- Added new [DatabaseTestClient](https://saffier.tarsild.io/test-client.md) delegating the creating of the `test` database
for each connection string provided.

* No more needed to manually create two separate databases thanks to the client that does the
automatic management for you.

Changed

- This was supposed to go in the release 0.2.0 and it was missed. Updated queryset lookup
for functions allowing accesing the model functions from the manager directly.

Added

- New [Index](https://saffier.tarsild.io/models.md#indexes) object allowing the creation of internal SQLAlchemy indexes.

Changed

- Updated metaclass to validate the fields being added to `indexes`.
