Remove redundant namespace scoping

[tanaya-mankad]

When a namespace object is used inside its own namespace, it doesn't need a scoping prefix. e.g.

namespace ashrae205_ns
{
    void from_json(const nlohmann::json& j, LiquidComponent& x) \
    {
        a205_json_get<ashrae205_ns::LiquidConstituent>(j, *logger, "liquid_constituent", x.liquid_constituent, x.liquid_constituent_is_set, true);
    }
}

can just be

namespace ashrae205_ns
{
    void from_json(const nlohmann::json& j, LiquidComponent& x) \
    {
        a205_json_get<LiquidConstituent>(j, *logger, "liquid_constituent", x.liquid_constituent, x.liquid_constituent_is_set, true);
    }
}
