Python sidre interface features

List of python Sidre interface features:

• Export/package Axom's python libraries. (setup.py? pyproject.toml? others?)
• Create bindings for the rest of the C++ Sidre interface where possible
• Make the interface more pythonic (reference doc: https://peps.python.org/pep-0008/#function-and-variable-names)
• Integrate better with numpy (add support for more numpy data types) or other python libraries
• Add blueprint support
  • Enable/disable support if Conduit was/was not built with python support. Add when other Axom components have python support added (other components do not strictly require conduit+python support). EDIT: sidre requires conduit, so axom+python will require conduit+python.
• Check that we're not leaking memory
• Add support for iterating the groups/views/buffers
• Test python interface in Docker images (GHA)
• Test python interface on Windows
• Add support for custom structs / opaque types (if possible and desired. )
• (optional) Interoperate with other python bindings, e.g. conduit, blueprint, hdf5, mpi (?) EDIT: conduit, mpi added.
• (optional?) Expose, test allocations on device
