`PyCColorDialog.SetCustomColors` returns error without setting exception

[Avasam]

For all bugs, please provide the following information:

Expected behavior and actual behavior

Calling SetCustomColors should raise a descriptive exception, namely: TypeError: The argument must be a sequence of integers of length 1-16. But instead you get SystemError: error return without exception set.

Steps to reproduce the problem

import win32ui
win32ui.CreateColorDialog(0, 0).SetCustomColors()  # SystemError: error return without exception set
win32ui.CreateColorDialog(0, 0).SetCustomColors([])  # SystemError: error return without exception set
win32ui.CreateColorDialog(0, 0).SetCustomColors([0])  # OK
win32ui.CreateColorDialog(0, 0).SetCustomColors((0,0))  # OK
win32ui.CreateColorDialog(0, 0).SetCustomColors((0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0))  # SystemError: error return without exception set
