FileNotFoundError is raised if only misspelled filename is passed to loading function witout a parent directory

If you are already in the directory of the file you want to upload with qim3d.io.load() and you misspell the filename, it raises the error:

FileNotFoundError: [Errno 2] No such file or directory: ''

But should raise 'ValueError("Invalid path")'

Example:

h5path = "small_fora.h5"

img = qim3d.io.load(h5path,virtual_stack=True,dataset_name='ex',return_metadata=False)
