Solving kwargs arguments verifications

[jposada202020]

After some verification, I add the **kwargs arguments to the LabelBase.

This was tested using slightly modified simple test to include and additional argument. will close #146

Test Code

import board
import terminalio
from adafruit_display_text import label


text = "Hello world"
text_area = label.Label(terminalio.FONT, text=text, WeTheNorth=True)
text_area.x = 10
text_area.y = 10
board.DISPLAY.show(text_area)
while True:
    pass
