win32clipboard increasing size of data when SetClipboardData used with CF_DIB

[cmdvmd]

• Expected behavior and actual behavior.

  When copying an image to the clipboard using CF_DIB, the size of the data should be the same both before AND after copying the image. However, the size of the copied image is 1 byte larger.

• Steps to reproduce the problem.

  Download the image.png file (or just any image file named image.png) and run the following Python script in the same
  directory:

  import win32clipboard
  
  with open('image.png', 'rb') as image:
      image_bytes = image.read()
  
  
  win32clipboard.OpenClipboard()
  
  win32clipboard.EmptyClipboard()
  win32clipboard.SetClipboardData(win32clipboard.CF_DIB, image_bytes)
  
  copied_bytes = win32clipboard.GetClipboardData(win32clipboard.CF_DIB)
  
  win32clipboard.CloseClipboard()
  
  print('Original image size:', len(image_bytes))  # 37257 bytes using attached file
  print('Copied data size:', len(copied_bytes))  # 37258 bytes using attached file

• Version of Python and pywin32
  Python: 3.11.4
  pywin32: 306
