Wheezewort vacuum cell at their root can be used to store infinite amounts of gases

I'm not sure if this behavior existed in previous builds, but the following exploit allows you to break "over pressure" rules.  

It seems that in the current build wheezeworts draw-in so much gas from their roots that they can create a permanent vacuum at their bases.   The gases are then released in the cells above the plant.  

This isn't particularly a big issue in normal cases... unless you encase the wheezewort in a very small room.   If you surround the plant on both sides, it will draw all of the gases below it, and push that gas into the space above it.

There are several cool features of this, such as the ability to control airflow without gas pumps or pipes, but the issue arises when the space above the plant is also surrounded by tiles.  Rather than the plant stifling because the space above it is over-pressure, it will continue to push the gasses below it into the space above it.

I can use this "feature" to capture and store large amounts of gasses without any sort of limit.
