[Feature]: Addition of iris and compatibility with opencomputers

[Geocube101]

Addition of energy shield and mechanical iris Addition of IDC Addition of iris related lua functions: (These are just concepts and as i don't know what arguments are required for these functions, these are just some possible names) "iris_open" sent to disengage iris/shield "iris_close" sent to engage iris/shield "iris_opened" activated when iris is opened "iris_closed" activated when iris closed "stargate_idc" activated during idc transmit (could return idc as string) "iris_impact" activated on iris impact When iris (or shield) is engaged, inbound entities are destroyed (and maybe the impact sound is played) (I know this is probably a lot, so you don't have to do it all right away) Really like this mod and keep up the good work
