swig 4.2.0 type errors in LALDetectors.h

@karl-wette @jolien-creighton @kipp.cannon @duncanmmacleod @adam-mercer In !2232 (merged) and !2232 (merged), the platform:conda:linux jobs fail with a long list of type errors from SWIGifying LALDetectors, specifically the "Detector DQ bit assignments enum. I suspect this will be due to the swig 4.2.0 version hitting conda with the new year (see https://anaconda.org/conda-forge/swig/files). Any easy fix ideas, or should we pin SWIG for the moment?
