pinion-pdf 1.0.0: rebuild a CSV from a spreadsheet printed to PDF

Derives page layout from the file itself (batch size, column edges, row
grid, labelling font), places text by start-x to survive cell overflow,
detects blackout redactions including filled-path bars and
single-character bars, and self-verifies via Excel's printed row-number
chain. Output byte-identical to four independently written
implementations across a 1,048,576-row reference file.

+measures the PDF before it reads it -- page size, column widths, column and
+row counts are all derived from the file -- rebuilds every row, detects
+blacked-out cells, and then checks its own working.
