Python Enum.IntEnum datatype do not fit on Tortoise.fields.IntEnumField when not int16

Describe the bug
Python Enum.IntEnum datatype do not fit on Tortoise.fields.IntEnumField when any element of enumeration is outside of int16 range.

IMHO, this should not behave like that (or at least configurable), since Python object can handle values larger than that.

To Reproduce

import enum
import tortoise.fields as fields

class PROTOCOL_ID(enum.IntEnum):
     A = 10000
     B = 80000

protocol_id = fields.IntEnumField(enum_type=PROTOCOL_ID)

Fails with

ConfigurationError: The valid range of IntEnumField's values is -32768..32767! 

Expected behavior
I expect that I could store values larger or smaller than int16 on that. Or at least a BigintEnumField. and SmallIntEnumField.

IMHO the naming should reflect the regular Int type fields as;

• Small = 16 bits
• Default = 32bits
• Big = 64Bits

Additional context
If not possible, is there a workaround? I do not want store that protocol static data into a database to increase the query complexity.

Python 3.9.7
Tortoise 0.17.8

Start at the Tortoise.fields.IntEnumField entry point and trace how it validates enum values against the int16 range. Check the related integer field behavior and tests. Done means IntEnum values outside the int16 range can be represented as requested, with coverage for the reported 10000 and 80000 values.
