Add PDF repair functionality

[microshine]

This pull request adds PDF repair functionality to the project. It includes the implementation of several repair rules and the necessary changes to the PDFRepair class. The PDF repair functionality allows for the detection and repair of various issues in PDF documents, such as incorrect EOL for cross-reference table entries and missing page references in annotations. This functionality will be useful for ensuring the integrity and correctness of PDF documents in the project.

const doc = await PDFDocument.load(raw);
const repair = new PDFRepair();
const report = await repair.checkDocument(doc);

switch (report.status) {
  case RepairStatus.requireClone:
    const clone = await doc.clone();
    break;
  case RepairStatus.repairable:
    await repair.repairDocument(doc);
    break;
  case RepairStatus.notNeeded:
    // No repair needed
    break;
}
