New persistency configuration
To go with LHCb!3268 (merged)
Persistency configuration updated to use new un/packers and writer/decoders.
Main changes:
- Un/PackParticlesAndVertices algorithms are removed. All packers are functional so need proper input and outputs.
- For packing input locations are collected from line dependencies.
- Output locations simply take a "p" in front of location name after stream.
- For reconstruction objects, they are packed to predefined packed location.
- For unpacking, locations are set in PyConf/reading.py
- Packing and serialization steps are simplified as everything configured in PersistRecoConf.
