`weaponinfo` to DH port

[elf-alchemist]

Given the "reference material" nature of the existing decohack code, perhaps it may prove useful to have ports of the weaponinfo states/info tables as well

For Doom these are fairly simple:

https://github.com/chocolate-doom/chocolate-doom/blob/3e0cd5dc0cd0d5b6788100a2fbc1cdd4ce014b35/src/doom/d_items.c#L37-L120

Heretic added some extra complexity, introducing the upgraded weapons concept, with different values for each -- not to mention the seeminglynew "holdattackstate".

Hexen's appears to be a bit simpler than Raven's prior release, but is still a bit numerous due to the class system -- the "holdattackstate" is still present, here.

Strife's loops back to being on the simpler end, like Doom's, with the only gotcha being a non-issue, whether or not the weapon is available in the demo version of the game:

the de-dehacked branch now outputs weapons for doom. it uses a hardcoded table for the weapons since it's simpler than writer another parser. the code for generating the state machine is now generic for weapons/mobjs. the script got a rewrite for this branch, so its now in infohack/infohack.py. it also has some support for generating the decohack for doom + a dehacked patch.
