WIP: adding a filterPersister (a filterpredicate that saves its decision in TES)

for discussion:

In order to implement DECReports, we would like to store the output decision of a filter into the TES, so that another algorithm (DecReportsWriter) can work with these. Here I propose a FilterPersister, which is basically a FilterPredicate with a outputLocation, writing its decision to TES.

Happy to discuss completely other approaches to handle DecReports or different approaches to write the filterPassed to the TES.
