The EVPath package has no COMPONENTS.  The existing use of them for
EVPath was probably accidentally copied from the HDF5 dependency.

The C test should use `MPI::MPI_C`, not `MPI::MPI_CXX`.

Fix reorg local arrays

adios_reorganize can convert Local Array variable if it has exactly 1 block. Otherwise, it will quit with a meaningful message instead of segfault. Related to issue #2033.

Fix InSituMPI crash on big-endian platforms

fixed a bug in ssc reader and added more common staging tests

bring some common-staging tests back to SSC

Fix a few multi-stream issues in SSC and add tests for xgc-coupler-gene use case

Fix unaligned memory access in SSC engine

Add MpiHandshake to enable XGC-COUPLER-GENE communication pattern

bindings: Convert Fortran MPI- and non-MPI implementations to submodules

Convert the separate modules implementing Fortran `adios2_init` and
`adios2_open` generic procedure signatures for MPI and non-MPI variants
into submodules.  This allows the primary modules to be built first and
the implementation submodules built later in separate libraries.

In order to support compilers that do not support Fortran submodules,
use preprocessor conditions to optionally build without submodules as
before.

This will be useful later to add preprocessor conditions to the
implementation sources.

Readme: Conda Badge

Add a badge to install ADIOS2 via conda-forge.
By default, conda-forge packages install without MPI. The user can
control variants via:

- `conda install -c conda-forge adios2` default, nompi variant
- `conda install -c conda-forge adios2=*=mpi*` any mpi-compatible implementation
- `conda install -c conda-forge adios2=*=mpi_mpich*` pick mpich variant.
  Same result as `conda install -c conda-forge mpich adios2=*=mpi*` .
- `conda install -c conda-forge adios2=1.13=nompi*` explicitly forbid MPI.
  Usually not necessary, as the build number offset causes `nompi` to be preferred unless MPI is explicitly requested.
