Remixware v0.3.2

Two fixes in the dependency gate, found while recording the case studies.

• With deps.lockfiles set, a lockfile outside the list that a change adds
  or edits is now not-checked, which fails by default. Before, it wasn't
  read at all, so a new requirements file with packages or an
  --extra-index-url passed without a word. The message names the file
  and says how to add it to deps.lockfiles or leave it out on purpose
  with the policy's ignore. Files a listed requirements file reads with
  -r or -c count as read.
• A requirement with no version shows as unpinned, in the text output
  (pypi/neuronx-cc unpinned, added) and in the JSON ("to": ["unpinned"],
  and in from). It showed an empty version before.
