Parallelization of pmid inventory code

[joshlawrimore]

• Write steps of getting biowulf/helix setup to run inventory in a README.md file on the repo. Reference slack conversation...
• Update the services\oddpub\definition.def file to fix the startscript and runscript issue. Figure out a way to pass the tunnel port to the script when we run it
• Test ways to create tunnels using sbatch job to automatically create oddpub singularity containers with tunnel ports opened correctly
