Add better representation for Color object

[jjeff07]

I am trying to print out data models that use the Color class however the repr unlike BaseModel is showing rgb=XXX which is not valid for initilization.

from devtools import debug
from pydantic_extra_types.color import Color
color = Color('red')
"""
debug(color)
<input>:1 <module> (no code context for debug call, code inspection impossible)
    Color(
        'red',
        rgb=(
            255,
            0,
            0,
        ),
    ) (Color)
Color('red', rgb=(255, 0, 0))
"""
Color('red', rgb=(255, 0, 0))
Traceback (most recent call last):
