Dual mode MS2Deepscore model (MS2DeepScore >2.6)

MS2DeepScore model compatible with MS2DeepScore >=2.6.

An MS2Deepscore model trained on both positive and negative ionisation mode spectra. It is suitable to predict chemical similarity between two mass spectra, both between the same ionmode, but also between positive and negative ion mode spectra.
