Option to cache input data cannot be used with XRootD prefixes

[vepadulano]

The function used to cache the input files on user's request only works with https based paths

Lines 27 to 33 in b4625ae

	def cache_files(file_paths: list, cache_dir: str, remote_prefix: str):
	for url in file_paths:
	out_path = Path(cache_dir) / url.removeprefix(remote_prefix).lstrip('/')
	out_path.parent.mkdir(parents=True, exist_ok=True)
	if not out_path.exists():
	with tqdm(unit='B', unit_scale=True, unit_divisor=1024, miniters=1, desc=out_path.name) as t:
	urlretrieve(url, out_path.absolute(), reporthook=_tqdm_urlretrieve_hook(t))

We could support also caching files in case XRootD paths are used
