Issue:
Wrong extracting of XML list nodes

Example:
xml"""<a><b>1</b><b>2</b><b>23</b></a> """.b.as[List[Int]] // List[Int](1, 2, 23); - is ok
xml"""<a><b>1</b><b>2</b><b>23</b></a> """.b.as[List[String]] // List[String](1, 2, 23); - not ok
xml"""<a><b>1</b><b>2</b></a> """.b.as[Int] //res2: Int = 12 - not ok
xml"""<a><b>1</b><b>2</b></a> """.b.as[String] //res2: String = 12 - not ok

Expected:
xml"""<a><b>1</b><b>2</b><b>23</b></a> """.b.as[List[String]] should lead to rapture.json.TypeMismatchException:t ype mismatch: Expected string but found number

xml"""<a><b>1</b><b>2</b></a> """.b.as[Int] should lead to rapture.xml.TypeMismatchException: type mismatch: Expected number but found array

xml"""<a><b>1</b><b>2</b></a> """.b.as[String] should lead to rapture.xml.TypeMismatchException: type mismatch: Expected string but found array
