Property type in trigger lines

Whatever is the type of a property of a trigger line, one has to pass a string in the python file. One example can be seen in the di_muon_low_mass_line. The property is of type float and is defined here : https://gitlab.cern.ch/lhcb/Allen/-/blob/master/device/selections/lines/include/DiMuonMassLine.cuh#L35 However, when called in the HLT1Sequence, one has to pass a string as shown here : https://gitlab.cern.ch/lhcb/Allen/-/blob/master/configuration/sequences/definitions/HLT1Sequence.py#L367 It would be more intuitive to be able to pass an object of the correct type in the python file.
