Bitwise operation is not supported by Conditional

[dzvancuks]

Unfortunately classes ConditionParser and ExpressionEvaluator do not support bitwise operations such as flag parsing

My_Field
    u8    flags    0
    conditional    flags & ${0x00000001}    conditional_field    # Same for 'flags & ${0x00000001} != 0'
        My_Conditional_Field
    end conditional

Errors are:

IllegalConditionException: Unsupported operation: flags & 1
IllegalConditionException: Given name condition: flags & 1 not found in message fields
