Adding long string of text fails

[n-i-x]

Describe the bug
Adding text to an image fails with the error:

Traceback (most recent call last):
  File "/workspaces/turing-smart-screen-python/button_card.py", line 50, in <module>
    lcd_comm.DisplayText(game['gamename'], 5, 5,
  File "/workspaces/turing-smart-screen-python/library/lcd/lcd_comm.py", line 273, in DisplayText
    self.DisplayPILImage(text_image, left, top)
  File "/workspaces/turing-smart-screen-python/library/lcd/lcd_comm_rev_c.py", line 303, in DisplayPILImage
    img, pyd = self._generate_update_image(image, x, y, Count.Start, Command.UPDATE_BITMAP,
  File "/workspaces/turing-smart-screen-python/library/lcd/lcd_comm_rev_c.py", line 365, in _generate_update_image
    payload.extend(bytearray.fromhex(image_size))
ValueError: non-hexadecimal number found in fromhex() arg at position 5

To Reproduce
Steps to reproduce the behavior:

lcd_comm.DisplayText("1000 Miglia: Great 1000 Mile", 5, 5,
                                font="geforce/GeForce-Bold.ttf",
                                font_size=60,
                                font_color=(255, 255, 255),
                                background_image=background,
                                align="left",
                                anchor="lt")

image_size from line 365 in _generate_update_image = '10ff3'. It appears that when the value is more than 4 bytes there is an error.

Expected behavior
Text should render on the screen.

Screenshots / photos of the Turing screen
Nothing displays.

Environment:

• Smart screen model Turing 5
• Revision of this project main branch
• OS with version OSX 14.2.1
• Python version 3.9
• Hardware MacBook Pro M3 Pro

Additional context
I attempted to zero pad the string but that didn't work. Reducing the string below the size that ends up being 5 bytes works fine.
