Use list form of fs.put() in LocalTempFile to avoid isdir() checks

[aabmass]

Calling put with lists like put([a], [b]) avoids the expensive path expansion in AbstractFileSystem/AsyncFileSystem

filesystem_spec/fsspec/spec.py

Lines 1049 to 1051 in 7aa982a

	if isinstance(lpath, list) and isinstance(rpath, list):
	# No need to expand paths when both source and destination
	# are provided as lists

In particular this avoids calling isdir() which can be really expensive in object stores like gcsfs. Concretely it saves 3 GET requests in each commit through a simplecache chained to gcsfs. See fsspec/gcsfs#702 for additional context.

Perfect, thank you.
