TAE handling for EvtStoreSvc

Error event handling

See merge request !3883

Fix ODIN::CalibrationTypes and clean up

See merge request !4514

A successful event after a failed one got a failure StatusCode
because of how the AlgExecStateSvc works. An extra reset fixes that
problem.

By default we stop after the first failure.

Add a test to check skipping isolated events works (StopAfterNFailures > 1).

define unpackers_map in the one module which uses it

- Remove the need for upfront_decoder.bind( source = ... ): compute the relevant argument from the requested location in _get_unpacked and pass it explicitly
- Remove ability to pack using deprecated, old-style 32-bit references which are known to overflow and lead to data corruption - only keep the ability to pack 64-bit references. Throw an exception if such an packing version still requested (note: the unpacking is left as-is)
- Improve implementation of packing and unpacking of references
- Unify setters in event model classes for SmartRef and pointer: remove redundant overloads (which could be ambiguous, and require additional casts!)

remove unused headers from Particle.h
