@pzagorowicz/react-awesome-query-builder v6.0.0-alpha.2

This is a fork of react-awesome-query-builder and it is based on react-awesome-query-builder@5.2.0, on top of this commit.

The main goal of this modification is to make it possible to use functions in the left-hand side operand of a query.

Implementation of this feature is experimental and it is based on the right-hand side (RHS) operand logic and components. It intruduces breaking change due to replacing field property in the query model with the new properties for left-hand side (LHS) operand: lhsValue, lhsValueSrc, lhsValueType and lhsValueError.
