## About The Pull Request

<!-- Describe The Pull Request. Please be sure every change is

merging your PR! -->

Granularizes mech equipment in the outpost catalogue and adjusts some of
the descs.

## Why It's Good For The Game

<!-- Please add a short description of why you think these changes would
benefit the game. If you can't justify it in words, it might not be
worth adding. -->

More fine control how much you need to order at the outpost is good. And
honestly? Who needs three drills?

<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
