Description

Building upon CAY-1693, let's create support for bit operations in String expressions. Parser BNF [1] need to be expanded to include &, |, ^, ~, hence allowing creation of these expressions via 'Expression.fromString(..)". Some examples of how those might look like:

someProperty & 3 = 1
someOtherProperty | 1 = 0
someOtherProperty ^ 1 = 0
~yetAnotherProperty = 1
someProperty & ~yetAnotherProperty = 1
