Pydantic models generation

[bogdandm]

Add pydantic converter:

json2models -f pydantic ...

Example (testing_tools/real_apis/f1.py):

from datetime import date
from pydantic import BaseModel, Field
from typing import List
from typing_extensions import Literal


class DriverStandings(BaseModel):
    season: int
    round_: int = Field(..., alias="round")
    DriverStandings: List['DriverStanding']


class DriverStanding(BaseModel):
    position: int
    position_text: int = Field(..., alias="positionText")
    points: int
    wins: int
    driver: 'Driver' = Field(..., alias="Driver")
    constructors: List['Constructor'] = Field(..., alias="Constructors")


class Driver(BaseModel):
    driver_id: str = Field(..., alias="driverId")
    permanent_number: int = Field(..., alias="permanentNumber")
    code: str
    url: str
    given_name: str = Field(..., alias="givenName")
    family_name: str = Field(..., alias="familyName")
    date_of_birth: date = Field(..., alias="dateOfBirth")
    nationality: str
