This is part of #8362 - I'm hoping to break down that PR into easier-to-review chunks.

	def loadImageSeries(filelist: list[str] \| None = None) -> list[SpiderImageFile] \| None:
	"""create a list of :py:class:`~PIL.Image.Image` objects for use in a montage"""
	if filelist is None or len(filelist) < 1:
	return None

	imglist = []
	for img in filelist:
	if not os.path.exists(img):
	print(f"unable to find {img}")
	continue
	try:
	with Image.open(img) as im:
	im = im.convert2byte()
	except Exception:
	if not isSpiderImage(img):
	print(f"{img} is not a Spider image file")
	continue
	im.info["filename"] = img
	imglist.append(im)
	return imglist

convert2byte() is a SpiderImageFile method, so the image must be a SPIDER image to call that
convert2byte() returns an Image instance, meaning that loadImageSeries returns a list of Images, not SpiderImageFiles.
