Adds a modular armour version of the explorer suit and adds sprites to specialist armour (#7921)

* Adds a modular armour version of the explorer suit.

* Adds material armour building steps for plates, arm guards and leg guards

Adjusts chitin hardness and weight (weaker and lighter)

* Maps a drying rack and washing machine into the planetside outpost

* Fixes QDEL issue, adds sprites to the specialist armours, and adjusts the cargo crates to match.

* Changes map format to TGM

* Removes flashy pixel on south facing leg sprites

* Adds proper returns, removes copypasta, fixes labeller & pen interactions
