Expose PDF.js getTextContent method via a Content property.

[yveszoundi]

This is a suggested implementation for #19.

Right now I roll pdf2json with a minor modification in the pdf.js script.

Thank you for your great work.

I can see the "content" property would be useful in certain use cases, but it doesn't fit into the current output format. Because the output format is designed to be a simplified structure that can be used to re-construct the PDF content (not just text, but also color, styles, lines, positions, sizes, fields, types, formats, etc.) in client renderer, and text content is already part of Texts property.

In case you only need Text from PDF, don't care about other content, I'd suggest to add another top level method that only returns text content.

I known the goal of your work is re-construct the PDF content. I need only for text but I really don't understand why Texts property contains ASCII character, for example 2C instead ','. Instead, If I use promise object from page.getTextContent() it returns clear text!

You did a great work.

I've got a couple of more inquiries on getting raw test content from PDF lately, reopen this pull request and merged it for more testing. Thanks for the contribution and sorry for the delay.
