Describe the bug
Tested in SimpleITK 2.3.1 and calling sitk.ProcessObject_SetGlobalWarningDisplay(False) does not suppress TIFFReadDirectory warning messages such as TIFFReadDirectory: Warning, Unknown field with tag 51123 (0xc7b3) encountered.

To Reproduce
Steps to reproduce the behavior:

1. Operating system, version, and architecture

• OS: [Rocky Linux 9 ]
• Architecture: [x86]

2. Programming language, and version [Python 3.10.13].
3. Version of SimpleITK [2.3.1], output of the SimpleITK Version() function.
4. How was SimpleITK installed?

• binary distribution [e.g. python -m pip install SimpleITK]

5. A minimal working example which causes the error.
   Duplicate any image and load them in ImageJ as an image stack, then save as a tif file. The tif stack file will contain a custom tag of 50838 (0xc696). Then the SimpleITK.ReadImage function call will produce warning messages. Calling the ProcessObject_SetGlobalWarningDisplay(False) won't stop it. See the example below.

Expected behavior
Based on the SimpleITK documentation, calling sitk.ProcessObject_SetGlobalWarningDisplay(False) should suppress TIFFReadDirectory warning messages such as TIFFReadDirectory: Warning, Unknown field with tag 51123 (0xc7b3) encountered.
