[MIRROR] Exosuit Proto-kinetic Accelerator (#7231)

* Exosuit Proto-kinetic Accelerator (#60384)

Adds new equipment for mechas: the Exosuit Proto-kinetic Accelerator, unlocked with the mining tech research. Compared to the standard one, it is able to hit 5 tiles away with a low cooldown.

However, unlike the handheld version, it draws a considerable amount of power from the battery, pretty much requiring you to bring generator equipment or upgraded parts.

The projectile is identical to the standard handheld version otherwise and will do little damage in pressurized environments.
