[Bug]: on a Mac when loading extensions the sidecar ._mycode.py file will be loaded causing a ValueError: source code string cannot contain null bytes error

Is there an existing issue for this?

[X] I have searched the existing issues and checked the recent builds/commits

What happened?

The extension I was developing kept failing to load with ValueError: source code string cannot contain null bytes after much testing I determined the problem was a hidden side car file

user@xxx scripts % ls -ltra total 1024 drwxrwxrwx 1 xxx staff 131072 Jun 29 21:30 . drwxrwxrwx 1 xxx staff 131072 Jul 6 14:41 .. -rwxrwxrwx 1 xxx staff 4096 Jul 6 14:42 ._alpha.py -rwxrwxrwx@ 1 xxx staff 10 Jul 6 14:45 alpha.py

short term fix, delete files before running webui.sh long term fix, can you exclude loading .* hidden files in the module load code

Steps to reproduce the problem

Go to .... extensions/xxx/scripts. , create alpha.py on a Mac using an editor that creates sidecar files (brackets,xcode..)
run webui.sh
...

What should have happened?

it would be nice if .xxxxxx.py was ignored and not loaded as python code
