Changes to make SciMLSensitivity work

[albangossard]

As part of the changes required to make both Enzyme and SciMLSensitivity work with our code (ODINN-SciML/ODINN.jl#350 and ODINN-SciML/Huginn.jl#94), I added θ as an explicit argument in all the functions involved in the SIA. This PR reflects this change.
