Correct state transitions to match states

[marcadella]

LUH2 gives provides time series of both state vectors and a transition matrices. The approach being taken is to use the state vector of the initial year and apply the transition matrices to reconstruct the states at ulterior years. That is we ignore the states provided by LUH2 (except the initial one). The goal of this issue is to:

• Verify how much the generated states diverge from the LUH2 states. If they fit perfectly we can stop here.
• If not, find a heuristic to reconciliate both.

NOTE: Biomee (Fortran) assumes corrected states and transitions as input, so any check or correction has to happen in R.
