Add spider-leg prototype names to spidertron's LuaEntityPrototype

[Stringweasel]

What

For a spider-vehicle extend LuaEntityPrototype to contain the names of the spidertron's leg prototypes.

For example:

Code: Select all

spider_legs :: array[String]?	[R]  | The prototype names of each of the spider-vehicle's legs.

I don't mind about all the SpiderEnginePrototype information, and only really need the prototype names. I'd rather only have the prototype names than nothing

Why

For spiders the most important collision behaviour is contained in the legs which makes it really important to be able to access the leg prototypes for a specific spider type. Currently it's only possible to determine the names using spider.get_spider_legs(), but's that's only possible if you have the spider entity already, which is often not the case.

My current workarourd is to create a temporary spider, get the leg, get the collision mask, and then destroy it again. It's a really ugly workaround though, and would love if I can save others from having to do the same
