      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
