Abstract method StorageObjectBase.local_suffix missing return type

[Hugovdberg]

The code for StorageObjectBase.local_suffix is missing a return type, while the concrete implementation
in the readme returns str. This raises an incompatible method override error on type checking. Is this always supposed to return a string? Or are there other valid return types for the abstract method?

Abstract method:

snakemake-interface-storage-plugins/snakemake_interface_storage_plugins/storage_object.py

Lines 99 to 105 in a07d750

	@abstractmethod
	def local_suffix(self):
	"""Return a unique suffix for the local path of the object."""
	# This can be a hexdigest of the query, or ideally a meaningful name.
	# For example, if the query is a URL, it can be the URL without the protocol
	# part and any optional parameters if that does not hamper the uniqueness.
	...

Example implementation:

snakemake-interface-storage-plugins/README.md

Lines 146 to 148 in a07d750

	def local_suffix(self) -> str:
	"""Return a unique suffix for the local path, determined from self.query."""
	...
