Update to v0.9.16.1

This was my first encounter with any Lisp language, so I'm sure my code there could be improved.

Additionally, while testing this I noticed the following gaps/issues that I wasn't Lisp-proficient enough to fix:

• Firelight missile bank stats don't work, because it's got a weird two-stage projectile and the following in src/clj/endless-ships/outfits.clj only traverses one stage:

                    :weapon (-> weapon-attrs
                                (get-in [0 1])
                                ->map
                                (assoc :submunition (get-in weapon-attrs [0 1 "submunition" 0 0])))

• Langrage Hyper-Heaver stats are messed up, although it's a complicated weapon so not sure it's worth fixing.

I also was hoping to do the following, but couldn't figure out how to do it:

• Label outfits by race (pass the data subdirectory along when collecting data files?)
• Label outfits by whether they can be purchased (may require inversion or re-processing with the outfitters output, currently only done on the frontend)

(this was split from https://github.com/7even/endless-ships/pull/12)

force-push fixed some accidental tabs, converted back to space to be consistent with the rest of the repository
