.create and .serialize ignoring json casts

[circulon]

Describe the bug
Adding a JSON cast to a models attribute I would expect a create to serialise the List assigned to the attribute into a string before saving.

To Reproduce
Note the "roles" column type is set as JSON on the db table

Steps to reproduce the behavior:
Model example:

class Employee(Model):
    __table__ = "employee"

    __casts__ = {"roles": "json"}

    __fillable__ = [
        "email",
        "roles",
    ]


# create the model
emp = Employee.creat({
    "email": "test@domain.com",
    "roles": ['admin', 'user'],
})

throws error similar to the following:
the JSON object must be str, bytes or bytearray, not list

Interestingly if I remove the casts and dump to json myself like this
"role": json.dumps(['admin', 'user'])
everything works as expected.

Looking at the JsonCast class it only passes 'dict' objects through
Ideally this should include lists as the json for them (like dicts is a direct correlation

Expected behavior
the list should be serialised and deserialised transparently in the model.
