The allow_null parameter is not passed in rest framework SchemaField

[noamkush]

When using allow_null with rest framework SchemaField, the implementation does not pass the parameter to the base class so we get the default which it False. The fix is simple but I was wondering whether I'm missing something here. Here's a reproduction:

from django_pydantic_field.rest_framework import SchemaField
from rest_framework import serializers
import pydantic


class Foo(pydantic.BaseModel):
    slug: str = "foo_bar"


class MySerializer(serializers.Serializer):
    foo_field = SchemaField(schema=Foo, allow_null=True)


serializer = MySerializer(data={"foo_field": None})
serializer.is_valid(raise_exception=True)

This gives:

ValidationError: {'foo_field': [ErrorDetail(string='This field may not be null.', code='null')]}

Hey @noamkush

I prepared a small fix in #70, will release a patch to PyPI later today.
Thank you for reporting this issue!
