Changes

• Support for Slurm 22.05.X (#238)
• Now actually link to libslurm.so instead of libslurmfull.so (#238)
• Add a pyproject.toml to ease installation (#239)
• Allow specifying Slurm lib-dir and include-dir via environment variables on install (#239):
  • SLURM_INCLUDE_DIR
  • SLURM_LIB_DIR
• Removes the stats key from the job-allocation dictionary itself when doing slurmdb_jobs.get(). Support for it was removed upstream here. (stats for job-steps are still accessible though)
