Jonas Jenwald 7728a6630c Inline the isString check in the Parser.getObj method 
For very large and complex PDF files this will help performance *slightly*, since `Parser.getObj` is called *a lot* during parsing in the worker.

This patch was tested using the PDF file from issue 2618, i.e. http://bugzilla-attachments.gnome.org/attachment.cgi?id=226471, with the following manifest file:
```
[
    {  "id": "issue2618",
       "file": "../web/pdfs/issue2618.pdf",
       "md5": "",
       "rounds": 200,
       "type": "eq"
    }
]
```

which gave the following results when comparing this patch against the `master` branch:
```
