Invalid type map class throws InvalidArgumentException

FYI: I'm not using the exception messages in this spec. Let me know if you'd like me to update the test cases to what we have in mongodb/mongo-php-driver#64:

• "Class %s does not exist"
• "Class %s is not instantiatable"
• "Class %s does not implement %s\Unserializable"
• "Expected bsonSerialize() to return an array or stdClass, %s given" (where %s is the class name or non-object's PHP type)

I'm not using the exception messages from the spec either :-)

I don't quite see why you need all of these though? For the first three, I just use "The typemap does not provide a class that implements MongoDB\BSON\Unserializable". I don't actually validate when parsing the typemap. Why is that needed?

I figured that the extra messages would help users catch their problem. Putting in the class name in the exception message helps, too.

API-wise, I think throwing an InvalidArgumentException is enough, though, since we're not using codes.
