Update marshmallow-sqlalchemy to 0.22.0

[pyup-bot]

This PR updates marshmallow-sqlalchemy from 0.21.0 to 0.22.0.

Changelog

0.22.0

+++++++++++++++++++

Features:

* Add ``SQLAlchemySchema`` and ``SQLAlchemyAutoSchema``,
which have an improved API for generating marshmallow fields
and overriding their arguments via ``auto_field`` (:issue:`240`).

.. code-block:: python

  Before
 from marshmallow_sqlalchemy import ModelSchema, field_for

 from . import models


 class ArtistSchema(ModelSchema):
     class Meta:
         model = models.Artist

     id = field_for(models.Artist, "id", dump_only=True)
     created_at = field_for(models.Artist, "created_at", dump_only=True)


  After
 from marshmallow_sqlalchemy import SQLAlchemySchema, auto_field

 from . import models


 class ArtistSchema(SQLAlchemyAutoSchema):
     class Meta:
         model = models.Artist

     id = auto_field(dump_only=True)
     created_at = auto_field(dump_only=True)

* Add ``load_instance`` option to configure deserialization to model instances (:issue:`193`, :issue:`270`).
* Add ``include_relationships`` option to configure generation of marshmallow fields for relationship properties (:issue:`98`).
Thanks :user:`dusktreader` for the suggestion.

Deprecations:

* ``ModelSchema`` and ``TableSchema`` are deprecated,
since ``SQLAlchemyAutoSchema`` has equivalent functionality.

.. code-block:: python

  Before
 from marshmallow_sqlalchemy import ModelSchema, TableSchema

 from . import models


 class ArtistSchema(ModelSchema):
     class Meta:
         model = models.Artist


 class AlbumSchema(TableSchema):
     class Meta:
         table = models.Album.__table__


  After
 from marshmallow_sqlalchemy import SQLAlchemyAutoSchema

 from . import models


 class ArtistSchema(SQLAlchemyAutoSchema):
     class Meta:
         model = models.Artist
         include_relationships = True
         load_instance = True


 class AlbumSchema(SQLAlchemyAutoSchema):
     class Meta:
         table = models.Album.__table__

* Passing `info={"marshmallow": ...}` to SQLAlchemy columns is deprecated, as it is redundant with
the ``auto_field`` functionality.

Other changes:

* *Backwards-incompatible*: ``fields_for_model`` does not include relationships by default.
Use ``fields_for_model(..., include_relationships=True)`` to preserve the old behavior.
