style: run clang format (#488) #173

	# Run clang-format
	# This workflow runs clang-format to format C++ code and then creates
	# a pull request to commit the changed files to the main branch.
	# More details about clang-format can be found here:
	# https://clang.llvm.org/docs/ClangFormat.html. To style
	# C++ code in VS Code locally, you could follow the instructions on this
	# website https://code.visualstudio.com/docs/editor/codebasics#_formatting
	# to format the entire file or selected text.
