Ability to hook onto electrolytic breathing unit for other modules on armor

[wolfieboy09]

Describe the feature you'd like

I have a module that tells Northstar that the body armor can be filled with oxygen. It stores this information with NBT on the armor.
I recently received a feature request (that I also planned before) where the same module can fill up the oxygen on the body armor so you don't need to put it in the oxygen filler block constantly.

This feature would allow other modules to get some form of event from the EBU for this module to listen to for said things.

Other modules could also create and send events for listened onto events by other modules for example as well.
