valohai-utils vfs mangles paths with archived inputs

[JuhaKiili]

When auto-processing an archived input (they are auto-processed by default), valohai-utils mangles the path and the name of the archived files.

Often there is information encoded into the path or filename (example: labels/UUID.json) that is now lost.

This code

import valohai

inputs = {"labels": "/home/juha/ws/yolov3-tf2/labels.zip"}
valohai.prepare(step="test", default_inputs=inputs)
for label_path in valohai.inputs('labels').paths():
    print(label_path)

With this zip contents:
