unique-labels reports false-positives when multiple documents are present in the repository.

Thank you for sharing this useful project!

I usually collect thematically related LaTeX documents in a single repository with one .tex file per document. This works perfectly well with the whole hook suite, except for unique-labels:

If I've got, e.g., two documents with an introduction section each, both labelled \label{sec:introduction}, the hook will report it as duplicate and prevent the commit.

I would like to propose adding an optional flag --individual to unique-labels causing the hook to perform the check on each file individually. You could invoke it like this:

    hooks:
      - id: unique-labels
        args:
            [
              "--individual"
            ]

I know, this is not an ideal solution, but it would help cover my use case. See the pull request #176 for an implementation that works as described.
