Review Comment:
How about keeping the original interface while adding a helper that using
lru_cache?
```python
@staticmethod
@lru_cache
def _manifests(io: FileIO, manifest_list: Optional[str]) ->
List[ManifestFile]:
if manifest_list not in (None, ""):
file = io.new_input(manifest_list)
return list(read_manifest_list(file))
return []
def manifests(self, io: FileIO) -> List[ManifestFile]:
return Snapshot._manifests(io, self.manifest_list)
```
Adding an additional argument breaks the public API.
