## About The Pull Request

halves the reagent requirements & hydrogen output for dimorlin since
they are all even
the amount of dimorlin output from the recipe is unchanged (at 2),
resulting in doubled output. The original pr had an output buff (2-4)
but it was committed after the pr entered the merge queue so it wasn't
merged

## Why It's Good For The Game

Makes painkiller mechanics easier to use by making the recipe more
efficient

## Changelog

:cl:
tweak: mixing dimorlin now requires half the required reagents, meaning
the same amount makes twice as much
/:cl:

<!-- Both :cl:'s are required for the changelog to work! You can put
your name to the right of the first :cl: if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the

changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
