Reworks flechette into a AP pellet round that does mostly wounds. Adds the Donk Co. 'Donk Spike' flechette round as a surplus round. (#89972)

## About The Pull Request

Reworks flechette shells from... whatever it was that they were supposed
to be before into an AP pellet round that primarily focuses on wounding
power and embedding power over specifically dealing direct damage (16 as
opposed to buckshot's 30). Useful if you want to maim as a priority.

You can print flechette once science researches Exotic Ammunition.
Nuclear Operatives also get flechette rounds as a Bulldog Shotgun
magazine choice priced as a basic ammunition type.

In addition, you can also acquire Donk Co. 'Donk Spike' flechette
shells. These shells fire plastic darts! They can be purchased by
Nuclear Operatives as a surplus option for Bulldog shotguns. 7 magazines
for the price of one.

Donk Co. 'Donk Spike' flechette was intended to be an alternative to the
standard flechette but failed spectacularly once it hit the market. Due
to a lack of confidence in the product, Donk Co. 'Donk Spike' flechette
now appears in maintenance loot as potential trash, as Donk Co. dumped
it in the millions into various landfills across the sector.

You can also print it if you find the tech in a BEPIS tech disk. 

Does it work? Why don't you take a chance on Donk and find out?

## Why It's Good For The Game

I'm not sure if the person who made the original flechette actually
understood what each of the variables was supposed to be doing or how
they actually worked. A bullet with an excessively negative standard
wound power (for a pellet projectile) and low damage, but then an
excessively high bare wound bonus (for a pellet projectile). But then
some ricochet variables without ricochet being assigned to the bullet...
and a demolition mod on a round meant to be weak against armor?

Nonsensical.

So I've reworked it into two unique rounds. The first serving a
practical purpose and becoming an AP option when the crew typically
begins seeing those options open up (such as x-ray lasers). The same can
be said for nukies, who love AP options, but one focused on lasting
wounds is handy too for keeping someone down. There isn't a milspec
option; so for nukies, this isn't doing nearly as much upfront damage as
buckshot or slugs. You buy this when you want someone not to be
recovered with a LOT of medical attention.

The second being more tongue in cheek, but also giving a surplus option
for Bulldog shotguns, which I think are having ammunition problems even
still. Surplus ammunition might slowly roll out for all the guns, but
I'm mostly focusing on the ones that have some slight price disparity
for total shots compared to other weapons. Also, shooting people full of
plastic is kind of funny.

## Changelog
🆑
balance: Flechette has been reworked into an AP pellet round that embeds
and wounds, but has less actual damage to buckshot. You can print it
once Exotic Ammunition has been researched. Also available to Nuclear
Operatives.
add: Donk Co. 'Donk Spike' flechette rounds. No longer offered by Donk
Co. It can sometimes shows up in trashbins and dumpsters. And operatives
can buy it in bulk if they really feel like it.
