feat: add explicit render priorities (#198)

* feat: static priorities

* refactor: assign all priority values

* chore: rocket and plunger priorities

* chore: rename priority class

* chore: add todo

* chore: remove todo

* refactor: move to separate file

* chore: uncomment score effects

* chore: revert spacing change

* refactor: update spaceship rail priority

* fix: issue in test from merge

* chore: add todos

* feat: add fire animation priority
