Missing PDFDocEncoding

[GreyWyvern]

The Adobe PDF Reference defines a special encoding which is an extension of Latin1 such that:

Informational or content strings can be represented in Unicode. These strings include text annotations, bookmark names, article names, document information, date strings, etc. In PDF 1.1 these strings are stored in PDFDocEncoding, which is a superset of ISOLatin1. PDF Reference 1.2 - https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/pdfreference1.2.pdf

See also: https://ia801001.us.archive.org/1/items/pdf1.7/pdf_reference_1-7.pdf

As this includes "document information" such as titles, authors and other details, PdfParser should use PDFDocEncoding to translate these strings.

Here is a proposed 'PDFDocEncoding.php' file I quickly mocked up but haven't tested yet. You can give it a shot; I will also see if I can create a branch where this works and submit a PR.
