> Currently, only {{StringType}} can be cast to {{BinaryType}}.
> Integer types also have a well known two's complement binary representation
> and can therefore be unambiguously cast to {{BinaryType}}.
> This PR adds support for casting
> * {{ByteType}}
> * {{ShortType}}
> * {{IntegerType}}
> * {{LongType}}
> to {{BinaryType}}.
