Is your feature request related to a problem? Please describe.
Currently on windows anything that "NOT ends with .exe, .cmd or .bat." will be filtered out.

My compiled test files are ending with an .out extension. This is due to other external requirements and cannot be changed, so I cannot have .exe or any other extension that would not get filtered out.

Describe the solution you'd like
I would like to have the option to set a regex matcher (or specify additional extension) which are not filtered out.

Describe alternatives you've considered
Currently I edit the main.js file manually and I add the .out text it to l=new Set([".exe",".cmd",".bat"]) (which is basically the win32NativeExecutableExtensionFilter variable in the source code)

Fixed in v4.8.3.

This issue was mentioned in CHANGELOG.md under a released entry so it is assumed to be fixed.
User verifications are always welcome.

Tested and works fine. I appreciate your help!
