doswim (mermaid borg) sprite bug fixes (#5299)

## About The Pull Request

This pull request fixes two bugs with the DoSwim (mermaid borg) sprites
for the three available variations (medical, science, and engineering).

The first (and more significant) bug was the sprite turning invisible
when EMP'd/flashed/buckled, this was caused by the icon_state using a
"-tipped" sprite that didn't exist.

/>
It now uses the "-sit" sprite in the files for this.

/>

The second bug was the science and medical variations not having overlay
sprites for cover open/cell out/wires exposed due to them being
presumably copy-pasted but still called "mereng" (also fixed).
