Adds space ticks to vent spawn event

About the PR

Adds space ticks to vent spawn event.

Why / Balance

Not enough variety in the vent spawn event, and ticks seemed to make sense as infestations on space stations.

They are fast, bunch up and inject a lot of poison, but are easy to take down with two or so crowbar swings.

Testing alone on Bagel, I killed about 9 or so ticks around the station. Most of them were alone but there were a few groupings of two or three.

They are very easy to dispatch but inject a lot of poison, probably won't pose as much threat compared to spiders

Maintainer team is discussing this type of PR at the moment, as merely adding a new vent creature event increases the overall chance for vent spawns, which can make that type of event happen more often than desirable. #32742 is an example of this being observed. We'll get back to you once the discussion has finished.

Is it not possible to just proportionally reduce weights for each new added vent event

Using the same spawn table is far easier than manually curating.
