https://developer.blender.org/rBa597d07011fca4b27b95d60067d902248be17cd9
Moved functions for constructing readers/writers based on cache library
out of pointcache into blenkernel.
This is quite simple and repetitive and there is not need to have this
in the main pointcache/Alembic API. The code is mostly concerned with
logic of DNA data, so pointcache shouldn't have to deal with it.
