Json assets

[danbuis]

Goal of Pull Request

Less monolithic assets for ships and squadrons.

Uses single purpose json files and reads those in instead of a large text file. Makes it easier to isolate malformed ship entries. Also makes a flatter pipeline. No text -> factory -> object. We can skip the middle step and have the constructor grab the right json file

Potential Tasks

• [x] Connects to #112
• [x] Meets the DefDone of the linked issue
• [x] All tests pass (Although the reviewer should run them to make sure)
