refactor: Replace Queue with @datastructures-js

[samestep]

Description

#796 added a custom class Queue to utils/Util. This PR deletes it in favor of @datastructures-js/queue, yielding two advantages:

• we don't need to maintain a queue implementation
• performance is increased by using an array instead of a linked list

This has a precedent in that we already use @datastructures-js/heap:

penrose/packages/core/package.json

Line 37 in ad7c57a

"@datastructures-js/heap": "^3.2.0",
