The rotation function https://github.com/icecube/skyllh/blob/130652f3724217c1ff9fa3080ba522ddbfb89608/skyllh/core/utils/coords.py#L6 does not preserve the relative declination difference between true and reco directions. This function is used in the class PointLikeSourceI3SignalGenerationMethod: https://github.com/icecube/skyllh/blob/130652f3724217c1ff9fa3080ba522ddbfb89608/skyllh/i3/signal_generation.py#L95
