BytesType.isValueCompatibleWith() previously accepted all types, including frozen collections and UDTs. This was incorrect because converting collections or UDTs to raw bytes is nonsensical - it allows reading raw serialized bytes which have no meaningful interpretation. This patch restricts BytesType to only accept simple scalar types by checking !isCollection() && !isUDT() in isValueCompatibleWithInternal(). patch by Dekrate for CASSANDRA-20982

Restrict BytesType compatibility to scalar types only
BytesType.isValueCompatibleWith() previously accepted all types,
including frozen collections and UDTs. This was incorrect because
converting collections or UDTs to raw bytes is nonsensical - it
allows reading raw serialized bytes which have no meaningful
interpretation.
This patch restricts BytesType to only accept simple scalar types
by checking !isCollection() && !isUDT() in isValueCompatibleWithInternal().
@driftx <- it was your task, I was happy to help!
