Add Boolean method to interpret byte value as boolean?

[Maurizio Cimadamore]

Yes - I think 0 == false has enough mathematical backing which would 
make sense to add it, IMHO. Other APIs do it too [1].

Also, if we had such a method, we could use it to adapt a byte returning 
VarHandle/MethodHandle into a boolean returning one.
