Feature Request: allow multiple files for stdin

Environment

• Tesseract Version: 5.0.1
• Commit Number: latest

Current Behavior:

Using cat file1.jpg file2.jpg | tesseract - stdout only handles file1.jpg. File2 is being ignored.
I know about filelists, but using a filelist is no option because of pre-processing; using cat is just a demonstration of the problem/bug.

Expected Behavior:

Both files are processed.

Combining image files with cat does not give a valid file which can be processed by any software. It's not a bug that Tesseract ignores the amended 2nd image.

I did not understand why a filelist is not an option for you. Could you please explain that a bit more?
