This commit introduces a new feature to extract and index metadata from collected PDF files.
The following changes have been made:
- Added a new `pdf` command with a `metadata` subcommand to extract metadata from a single PDF file.
- Added a new `extract-metadata` command to extract metadata from all PDF files within a given archive and create an `INDEX.json` file.
- Added a `--extract-pdf-metadata` flag to the `collect website` command to extract metadata from downloaded PDF files.
- Created a new `pdf` package to encapsulate the PDF metadata extraction logic, which uses the `pdfinfo` command from the `poppler-utils` package.
- Added unit tests for the new `pdf` package, including mocking the `pdfinfo` command.
- Modified `Taskfile.yml` to install `poppler-utils` as a dependency.
