output-as-text: add option to select output based on 'linked' print array entries

[ChHaeni]

At the moment, evaluation of the code say "\nFluxSummaryLivestock (Details)=\n", output-as-text($model, $output, 'de', 'FluxSummaryLivestock,TANFlux', True); will provide output from variables with a print array entry FluxSummaryLivestock OR TANFlux.
Please add the option to provide output only from variables with a print array entry FluxSummaryLivestock AND TANFlux. E.g. as follows:
say "\nFluxSummaryLivestock (Details)=\n", output-as-text($model, $output, 'de', 'FluxSummaryLivestock & TANFlux', True);
