improve astar perf (#1268)

## Description:

Created test that has astar pathfind from top left to bottom right of
giant world map.

* Before these changes: took ~950ms
* replaced queue with fastqueue library: ~600ms
* Changes heuristic to be more greedy (1.1 * dist => 2 * dist): ~90ms

Resulting in a roughly 10x improvement.

Other paths also saw improvements as well, although not as dramatic.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors
