Inconsistent BrowscapPHP::getBrowser() property types

When using the default formatter and invoking [https://github.com/browscap/browscap-php/blob/41d47ba71806dc059f2b8e3cc4ff94e4f1df399c/src/Browscap.php#L192]($browscap->getBrowser()] an object of type stdClass is returned, which has some properties defined.

The types of these properties seem not all parsed to a primary type. For example:

["crawler"] => string(5) "false" => value is a string
["ismobiledevice"] => bool(false) => value is a bool

A lot of boolean values are returned as string. Is this on purpose?
