Use Asyncio to execute

[mathben]

To increase speed of execution, I suggest to implement asyncio for each writer when command summary.

pygount/pygount/command.py

Lines 322 to 349 in fac7f7b

	def execute(self):
	_log.setLevel(logging.INFO if self.is_verbose else logging.WARNING)
	source_scanner = pygount.analysis.SourceScanner(
	self.source_patterns, self.suffixes, self.folders_to_skip, self.names_to_skip
	)
	source_paths_and_groups_to_analyze = list(source_scanner.source_paths())
	duplicate_pool = pygount.analysis.DuplicatePool() if not self.has_duplicates else None
	writer_class = _OUTPUT_FORMAT_TO_WRITER_CLASS_MAP[self.output_format]
	is_stdout = self.output == "STDOUT"
	target_context_manager = (
	contextlib.nullcontext(sys.stdout) if is_stdout else open(self.output, "w", encoding="utf-8", newline="")
	)
	with target_context_manager as target_file, writer_class(target_file) as writer:
	with Progress(disable=not writer.has_to_track_progress, transient=True) as progress:
	try:
	for source_path, group in progress.track(source_paths_and_groups_to_analyze):
	writer.add(
	pygount.analysis.SourceAnalysis.from_file(
	source_path,
	group,
	self.default_encoding,
	self.fallback_encoding,
	generated_regexes=self._generated_regexs,
	duplicate_pool=duplicate_pool,
	)
	)
	finally:
	progress.stop()

What do you think?

Probably makes sense although the error reporting might need some changes with possibly multiple readers/writers failing at the same time.

Not high on my priority list though, but I leave it in the backlog.
