Usage of the "@" character in the code - error suppression

Long story short, one of the PDF files I'm trying to parse throws an error - it basically cannot be parsed. Thing is that I cannot catch it with the standard try-catch block, because the parseFile() method from your package suppresses any errors thrown while parsing:

public function parseFile($filename)
{
    $content = file_get_contents($filename);
    return @$this->parseContent($content);
}

And the line in the Parser.php file: https://github.com/smalot/pdfparser/blob/master/src/Smalot/PdfParser/Parser.php#L74

I would say remove the @. And I would do it everywhere else you might have used it. What do you think?

Start with src/Smalot/PdfParser/Parser.php and inspect parseFile(), then search the project for other uses of PHP's @ error-suppression operator. Confirm the relevant parsing errors can propagate to the caller's try-catch handling without suppression.
