Larcv

This release is functionally the same as 3.3.0, but has some minor adjustments to the source distribution generation and other bug fixes. This will get uploaded to pypi.

This version does several things:
- IO Prefetching is now the default in QueueLoader.
- SWIG is out, pybind11 is in.
- numpy access to objects is more seamless with pybind11

Hopefully this deploys to pypi ...

This release is very similar to 3.2.0 with some minor fixes. Compiler warnings were addressed, and the linking error on Linux is also addressed as far as I can tell.

This is an incremental update to larcv3. It includes queue loader and many enhancements to the MPI loading compatibility. There are some very minor API changes that break compatibility of larch v3.0.0, but they are of the form of changing import files in python. larcv_interface needs to be replaced with thread loader, and the python object is now called thread_interface.

Tests for queue loader are included, but the data format is unchanged and files are 100% compatible with v3.0.0. There are no plans to modify the serialization API or data format.
