## About The Pull Request

As the name says, most ships had cell chargers but i've corrected those
i've seen.

## Why It's Good For The Game
I don't think cell chargers have any real reason to be rare. The cargo
pack is pretty expensive so it's not cheap to get a ton of chargers.
## Changelog

:cl:
add: Added cell chargers to more ships.
add: Added a cell charger cargo pack.

<!-- 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
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. -->
