Feature Suggestion: use Intellij's default reformat action when file extension is not supported by Clang-format

[wumo]

This is a great tool to replace clion's integrated reformatting function. So I set a global hotkey for clang-format. But clang-format will also reformat python files even though it doesn't know how to reformat python code. So my suggestion is: Add file extension filters, and let clang-format only runs on supported file extensions and redirect non-supported file to Intellij's default reformat action.
