COMPAS bundled Linux artifact

Supported platform:
- Ubuntu 22.04
- Linux x86_64

Contents:
- bin/COMPAS: bundled COMPAS executable
- lib/: shared libraries packaged with this build
- run_compas.sh: launcher that sets LD_LIBRARY_PATH for the bundled libs

How to run:
1. Unpack this directory on a supported Linux x86_64 machine.
2. From inside the unpacked directory, run:
   ./run_compas.sh -v

Notes and caveats:
- This bundle is intended to run without separately installing Boost, GSL, or HDF5.
- It still relies on the target machine's glibc and other base system libraries being compatible with Ubuntu 22.04.
- If you invoke bin/COMPAS directly, the bundled lib/ directory will not be added automatically; use run_compas.sh instead.
