Int default for float field causes avro_schema_to_python() to crash

[ghost]

Describe the bug

If you use an integer as the default value for a field declared as a float, avro_schema_to_python() will crash.

The problem here is that int is not a subclass of float, which is why this check fails. One way to fix this would be to make a special exception and say "if the field's type is a subclass of numbers.Real then allow an integer".

We could change this:

assert isinstance(default, a_type), msg

to something like:

assert isinstance(default, a_type) or (
    issubclass(a_type, numbers.Real)
    and isinstance(default, numbers.Integral)
    and not isinstance(default, bool)
), msg

(bool is a subclass of int which is why we need that last check.)

To Reproduce

from dataclasses import dataclass
from dataclasses_avroschema import AvroModel

@dataclass
class A(AvroModel):
    number: float = 0

# This will crash
A.avro_schema_to_python()

@dataclass
class B(AvroModel):
    number: float = 0.0

# This works fine
B.avro_schema_to_python()

Expected behavior

In the example above, A.avro_schema_to_python() should not crash, instead returning an equivalent (if not identical) schema to the one returned by B.avro_schema_to_python()
