Add tests for Run1 Sim10 workflow

Provides two new tests:

• moore.checkfsr.filter-sim10-2012-digi reads an unpacked 2012 Sim10 DIGI file and writes it out again after running HLT in Simulation mode
• brunel.checkfsr.validate-sim10-2012-fsr reads the file produced by the previous test, checks that the event containers structure is as expected and checks that the GenFSR is correctly propagated from the input file. The GenFSR reference is identical to that in the corresponding Boole test

N.B.:

• The stderr in filter-sim10-2012-digi.expected-stderr is expected, because we are reading with Root 5 a file produced with Root 6. The types which Root complains about are equivalent, so this is (or should be!) harmless
