Electron/Positron/Photon Propagation and inhomogeneous media

Feature

• add inhomogeneous media (add density axis), interpolation files are now independent of the density correction
• add electron/positron propagation (ionization, bremsstrahlung, annihilation)
• add photon propagation (photo pair production, Compton scattering)
• add sampling of individual energies in pair production
• add particle deflection in stochastic loss
• add ROOT interface
• Secondary class replacing Output vector
• add maximal distance for a step length
• add propagation to a minimal energy
• only_loss_inside_detector
• add just_use_readonly_path
• add ability to deactivate a cross section
• add CascadiaBasin SeaWater

Refactoring

• remove boost
• replace bimap
• create newton-raphson and spline method
• pybind parametrization factory
• no implicit movement of particle in Scattering
• move StochasticLoss calculation from Sector to utility
• now possible to propagate till the edge of all sector geometries
• particle is replaced by particleDef and particle condition
• upper limit calculation using newton raphson for distance energy

Bug Fixes

• numerical stable boosting in decay at high energies
• direction of decay products
• dr=0 in scattering
• energy conservation in decay products∂

Tests

• git-lfs
• add matrix element to Many Body Decay Channel test
