Unsound casting in flatbuffers

Details

The implementation of impl Follow for bool allows to reinterpret arbitrary bytes as a bool.

In Rust bool has stringent requirements for its in-memory representation. Use of this function allows to violate these requirements and invoke undefined behaviour in safe code.
