Avoid double stream reading

[Pol-Valentin]

Hi,

With colleague who is developping a symfony bundle to wrap your lib, we encounter a problem with the input stream reading in php5.5. In the php doc, it is said that we can't seek the input stream under php5.6 (refer to the note paragraph about "php://input"). So we propose to read only once the stream, it's also better for performance. For information we try to use it with zend diactoros, like recommended.

Thanks, really nice catch! I'll release a new patch version soon. By the way, I'll list your project in an integrations section of the readme :)
