Develop function to implement post-processing rules

[gilbertocamara]

After producing multi-year maps, it is important to develop transition rules that rule out impossible LUCC conversion (i.e., Clear Cut to Wetland). This could be implemented as a standalone R package, based on the papers

This has been implemented as the function sits_transitions() as an additional function to the sits package.
