Adds plasmaman screams (#73828)

## About The Pull Request
Adds sounds Farquaar made and posted on the forums as screams for
plasmemes https://tgstation13.org/phpBB/viewtopic.php?p=634202#p634202

After further incoherent screaming in the old folk's house Dragomagol
gave me permission to make everyone's life worse by making plasmemes
noisy
